Yes, for me it only starts gimp, without opening the actual file. To work out why would need looking at the source code, modifying, then recompiling. But, with latest release, v2.0, too many dependencies for me to be bothered:
configure: error: Package requirements (gtk+-2.0 >= 2.8.0 libxml-2.0 >= 2.4 gconf-2.0 >= 2.0 lcms dbus-1 exiv2 fftw3f lensfun libcurl flickcurl sqlite3 libssl libgphoto2 x11) were not met
That's a shame, I really want to try this one out... I tried to do it myself but fell at the first hurdle, gtk2.8 configured ok but then wouldn't make..and I don't know enough about anything to work out why...
