Gimp doesn't start

[NikoC]

Just installed gimp from ppa (ppa:matthaeus123/mrw-gimp-svn) and problem seems to be fixed!

It's a bug; #742516 at launchpad.
There is a workaround at Launchpad;
- change GTK+appearance to Rayleigh
- start Gimp and stop it
- change GTK+ appearance back to oxygen.

This seems to work for me.

Had the same problem, thanks.
I sort of remember doing this a while back, but I don't think it was for Gimp... I think I'm going to go try this in another computer that has an unrelated ubuntu issue, who knows, it might work!
