The application Plasma Workspace (plasma) crashed and caused the signal 11 (SIGSEGV)

[tdn]

Plasma crashes periodically. I have tried installing the dbgsym-packages, but I still get this "This backtrace appears to be of no use.".

Trace:

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.

Appearently, this happens every time I start a virtual machine with KVM/Qemu. I have no idea why.
