When trying to start GIMP, get a dialog:
GLib version too old (micro mismatch)
The GIMP requires GLIB+ version 2.4.5 or later.
Installed GLib+ version is 2.4.0
Somehow you or your software packager managed
to install The GIMP with an older GLib+ version.
Please upgrade to GLib+ version 2.4.5 or later.
This is from a straight-as-I-can-tell, standard-repository-updated Fedora Core
3, not testing or devel. I've seen this for months, just figured everybody would
see it and it would get fixed until I needed GIMP again. Apparently no FC users
use GIMP, or I have a more localized issue. :)
Be glad to do diagnostics or testing as needed.
Please include the exact versions of gimp, gtk2 and glib2 installed on your
system ("rpm -q gimp gtk2 glib2"). "Updated FC3" doesn't help me much as you
could either have updated from an out-of-sync mirror or I could have looked at
this only later with no easy way to determine what was up to date when you
issued this bug.
Using your command, I obtained this version info:
$ rpm -q gimp gtk2 glib2
No idea why I would have two glib2 packages installed, but doing
yum remove glib2-2.2.3-1
Remove: ORBit2-devel.i386 1:2.8.2-1
Remove: glib2-devel.i386 1:2.2.3-1
Remove: gtk2-devel.i386 0:2.4.14-2.fc3
Remove: pango-devel.i386 0:1.6.0-7
Update: glib2.i386 0:2.4.8-1.fc3
Update: glib2-devel.i386 0:2.4.8-1.fc3
which solved the problem, GIMP now starts for me.
