Binary package hint: rss-glx
I switched from one screensaver to another by pressing cursor-key-down.
The focus was in the screensaver list while I was searching for specific screensaver with which I wanted to reproduce another problem.
Then the screensaver crashed and the Apport application came up.
More information:
This assert was removed upstream 2009-09-20 with commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=284a7af274bc148f112bd0ebb40583923ee26b49
and in our mesa 7.6.0-1ubuntu1, but reintroduced in 7.6.0-1ubuntu3 to fix bug 446578. Upstream has applied the same fix (reverting 284a7af27) in 7.6.1, commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?h=mesa_7_6_branch&id=13b5a624b1899c457279907d58046dfb3c95addc
