Lost Gimp on upgrade

I recently upgraded to koala, but gimp no longer functioned after upgrade; i.e. open file popup dialogue freezes, crop tool is non-functional, preferences dialogue was absolutely a blank box. Tried un-install/re-install thru both the new software center and synaptic. Same broken result every time. Tried a direct download from gimp.org but ran into a lot of dependency stuff I know nothing about; I'm an end user, not a coder. So, how do I get a functioning install of gimp?
thanks,

Try opening terminal and typing:

Code:

---

sudo apt-get purge gimp ; sudo apt-get install gimp

---

Thanks for your quick response. But, I ended up with the same broken installation after running those commands.

Got a new clue:
The darned thing runs great if invoked with this command:
gksudo gimp

This does, however, generate a couple of warnings:

(file-uri:15160): GLib-WARNING **: g_set_prgname() called multiple times
WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect

(file-jpeg:15345): GLib-WARNING **: g_set_prgname() called multiple times

And, of course, I'm clueless on that.
