Comment 11 for bug 778414

Since I got the same bug (Kubuntu 11.04 - fresh install - fully updated), but solved it another way, here it is:
Got the segmentation fault error on starting gimp like this:
$ gimp

Then tried (I know .. "though shalt never do that" .. but I was curious):
$ sudo gimp
And that worked!

Did some research online and found, that for some people the problem seemed to originate from the ~/.gimp-2.6 - folder, because it was either missing or had the wrong permissions (root:root).

I found, that the only .gimp-2.6 - directory I had, was in /root/.gimp-2.6 .

So I did:
$ sudo mv /root/.gimp-2.6 /home/MY_USERNAME/.gimp-2.6
$ sudo chown MY_USERNAME:MY_USERNAME/.gimp-2.6 -R

This solved the problem of gimp crashing, but I still get the following message on starting gimp:
$ gimp

(gimp:3494): GLib-WARNING **: /build/buildd/glib2.0-2.28.6/./glib/goption.c:2132: ignoring no-arg, optional-arg or filename flags (8) on option of type 0

I guess that is fixable with changing to Raleigh, but I don't care to find out, since I can at least use gimp now.

Hope that comment is useful to someone, since the bug still seems to be alive and well.
