Bug 335026

Application: kactivitymanagerd (3.0)
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.28-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
there were several OpenGL Apps runned, one of them crashed several times with sigv. Tried to debug it with edb but when app hangs no keybrd inputs were possible. so, opened another tty, send hanging app and edb sigusr1, sigterm etc. to continue, at least not to coldreset machine. this went ca. 3/4-times, then i got frustrated and tired and decided to shutdown machine to get a fresh/clean opengl-stack and then, while shutting down: sudden-death! this happened.
kernel not crashed, just gfx-part, as usual in (meanwhile old?) kde  4.10.5; and always in context with opengl. hm. maybe should upgrade to OpenSuSE 13.1? ... hm.

- Unusual behavior I noticed:

OpenGL 3d app crashed, and even in debugger (edb) blocked keyb-inputs exept switching to other tty. hanging app leaves an open terminal which also hasnt keyboard. so, send sig term and restore X-resolution-settings.... i dont expect some changes or updates, i even didnt guess, which role makes kactivity in this context, but you asked so nice for crashreport ;-)
hope, you can use it, if not, auch gut... good bye
