Krita crashed right on start when my AIPTEK tabled is connected. 100% reproducible. Krita starts OK when the tablet is not connected. Gimp crashes too, but after some use. Inkscape works fine, TuxPaint works fine.

I don't have much time, but feel free to ask for information, for additional tests, etc. I'll be glad to help!
As I see som references to nvidia in the backtrace, here's what I have on ly system.

Sorry, but it's not useful to report bugs for Krita 2.8 anymore. I know it's what Debian ships, but it's just too old and out of date. Please try with a Krita 3.0.1.1 or the latest beta, 3.0.91 instead.
