Mavrothal,

Did you recompile Glib ? The glib with Precise is not compiled with gvfs support.

Maybe try deleting libpup-volume-monitor.so and libpup-volume-monitor.so.0 symlinks in /usr/lib/gio/modules/ ?

Yes. This solved this problem.
However, desktop_drive_icons does not work (see image). No errors anywhere. Any ideas?

Looks like the volume monitor is not working.

Can you see drive icon(s) in file chooser dialogs? (e.g. see screenshot in first post)

If no what type of device is sda1?
What is the output of blkid with sda1 connected?

The little square pointed with the red arrow in the picture above, is all I see.
Code:
# blkid
/dev/loop1: UUID="0a260d59-65a1-48c0-8f70-19e4fd9edae2" TYPE="ext2"
/dev/sda1: UUID="ad9e0ce4-3466-4eba-9956-217aaf2cf870" TYPE="ext2"

Updated to version 0.1.9

Changelog:
  • Disabled library versioning for GIO module, may fix 'two different plugins' error on precise puppy (thanks mavrothal)
  • Added support for extra debugging output by setting environment variable PUP_VOLUME_MONITOR_DEBUG. Currently it does almost nothing, in future this variable will make it print debugging info.

sda1 should have been detected.

Type pup-volume-monitor-admin -l in terminal and see whether sda1 is listed. If yes, surely the GIO module didn't load now. Try updating to latest version (before that uninstall previous version else you might run into the same 'two different plugins' problem again.) Or rename /usr/lib/gio/modules/libpup-volume-monitor.so.0.0.0 to libpup-volume-monitor.so, that may work.

If sda1 isn't listed, and sda1 is a removable drive, check presence of /etc/udev/rules.d/50-pup-volume-monitor.rules.

Else, this indicates some serious bug in pup-volume-monitor.

What I think is that precise GIO has changes not compatible with pup-volume-monitor, or atleast how desktop-drive-icons understands its output.
Original in precise gio-2.0.pc has:
Code:
Name: GIO
Description: glib I/O library
Version: 2.32.3
Requires: glib-2.0 gobject-2.0
Requires.private: gmodule-no-export-2.0
Libs: -L${libdir} -lgio-2.0
Libs.private: -lz   -lresolv
Cflags:

To compile monitor/icons I need to change it to
Code:
Name: GIO
Description: glib I/O library
Version: 2.32.3
Requires: glib-2.0 gobject-2.0 gmodule-2.0
Requires.private: gmodule-no-export-2.0
Libs: -L${libdir} -lgio-2.0 -lX11
Libs.private: -lz   -lresolv
Cflags:

Maybe there is a clue here?

IIRC one of the debian patches (maybe used by ubuntu too) removes an unneeded dependency on gmodule and thus libdl.so from libglib and libgio (it isn't really needed for gmodule unless gvfs or another loadable library is built in to gio and the patches ifdef a bunch of that), since some of puppy's libX11 also have the same unneeded dependency on libdl, that would explain why adding -lX11 would fix it, but my guess is that it really only needs -ldl and not -lX11 ... but explicitly link with gmodule which _should_ bring in -ldl on its own

its been a while since I looked at the source, so I may be way off track, but I seem to recall something loading as a module/plugin (which would indicate a dependency on gmodule)

It appears like gio is loading same module twice.

No idea how it happens. I tried exploring glib 2.32.3 sources but still no luck.

I have asked on gtk-list, maybe someone there can help us.

The mail can be viewed here: https://mail.gnome.org/archives/gtk-list/2012-October/msg00040.html

But there are many programs that use gmodule, right in puppy.

If it was possible to remove gmodule at all, then that should break many apps. gtk uses gmodule to load its theme engines. There are many other programs using gmodule to provide plugin support.

Just finished downloading precise, and I can now reproduce all precise-related problems.

I have confirmed GIO is loading same module twice, and it's a glib bug.

And it's affecting other distros using gvfs too. See here and here.

On examining stack carefully I caught GIO calling function which it isn't programmed to do in the source code.

Gray and technosaurus, you were right. glib that comes with precise isn't original glib-2.32.3, it's a modified glib-2.32.3 that can be found in ubuntu precise-updates suite. And that contains this bug.

I compiled glib, but with errors which I suppressed using -i option to make. And finally pup-volume-monitor works in precise Smile


I have made a pet, which isn't perfect due to errors, but it's good enough to make pup-volume-monitor work.

http://dl.dropbox.com/u/58347439/protected/glib-2.32.3-orig-imperfect-precise540-i686.pet

Edit: I managed to compile glib again, this time without errors.

The one on third post still has 0.1.9
