Okay, you installed Ktoon, it works flawlessly. Just one minor problem, there are no brushes, and about half the tools are non-existent.
I haven't used this program for almost a year because I just assumed it was an unstable problem, and I really didn't need it, so it's just lingered. Anyway, I finally wasn't so lazy to google it, and after perusing a few sites, I found this:
Basically, the fix is so complicated:
ln -s /usr/lib/ktoon/plugins/ /usr/share/ktoon/
Yes, in case you're wondering, I'm kicking myself now...hard!
Anyway, I figured in case somebody else gets caught on it, from what I saw it affects a lot of debian-based systems, perhaps more.
