**Krita_testing: test01**
Hi, finally got down to testing the Krita_testing version.
"krita-testing_2+git20151214+r45-61~ubuntu14.04.1_amd64.deb (36.0 MiB)"
https://code.launchpad.net/~dimula73/+archive/ubuntu/krita/+build/8438324

1.
Good news is, pressing the buttons does not crash Krita anymore. But something
is wrong, the first few times I tried, krita froze after pressing the button,
and the viewport turns into some transparency thingy state, but comes back to
somewhat normal state.. see url video 001. But it only happened in the first
few times, I can no longer replicate this effect.
VIDEO 001:(might be hard to see , sorry ...)

2.
I can however replicate a "pixelation with white edge" effect which only occurs
after button presses.
See video 002:

Git commit e749f160150a3d14ff0bfaad32607e17886b80fb by Boudewijn Rempt.
Committed on 13/12/2015 at 14:46.
Pushed by rempt into branch 'master'.

The Yiynova MVP20U+RH has hotkeys that generate some broken input,
and this patch corrects that down the line. I still want to know
what is broken, though.

You could also try to apply this patch. It doesn't fix what's wrong with the
input from the tablet, but it should fix the crash.

Hm, yes... But what's really needed is figuring out where the NaN parameters
come from. That is rather involved though, and means you'd have to put a
breakpoint in krita/ui/tool/strokes/freehand_stroke.cpp:76 and check at which
point we get the invalid data. Is that something you could try? If so, if you
could join us on irc, we might be able to help you.

Hm, that's interesting. The crash is an assert in the display code that happens
because we get a NaN for one of the parameters. We can check for that, but I
would really like to know what this tablet is actually sending to Krita.
Unfortunately that isn't in the log.

Well, then we must figure out what those buttons are sending... Try starting
Krita 
on the command line, and press crtl-shift-t to enable tablet debugging. Press
those
buttons and attach the output here.

Tablet Debugging and backtrace of Krita crashes

I tested the remote with GDB and Tablet Debugging running.
In the attachment are button presses of First, fourth, fifth and scroll center
button. Krita crashes instantly with just one press of any of these buttons.

I tried installing this build, see link below, however this build file is
rejected by the Ubuntu apt
"dependency is not satisfiable"

https://launchpad.net/~dimula73/+archive/ubuntu/krita/+build/8413495

this, even though this package is supposed to be fore ubuntu 14.04.

Hi,

Thanks for your report. Krita 2.8 is very old, though. Could you check whether
this issue still happens with Krita 2.9? You can install it the lime repo: with
