[Bug 366300] Re: plasma paint errors, crashes with SIGSEGV

Thu Apr 30 14:13:21 UTC 2009

Additional testing seems to support that these problems (graphical
corruption, plasma crashes) occur with multiple monitors, and do not
occur without them. I will update the description and systems affected
by the bug.

Is it the case that Kubuntu 9.04 does not work with multiple monitors?

Another crash, this time w/ more debug symbols installed:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.
