KWin in the host or the client? Is this reproducible? (It smells like memory corruption) In case it's reproducible, do backtraces look all the same? Ping? Sorry for the delay answering your questions. Here are answers: - kwin was running on my laptop - virt-manager was running on an ssh gateway (over ssh therefore) Today I managed to reproduce a similar bug while doing some other operations in virt-manager in the same context (that is over ssh). This is with KDE 4.11.3. Note that this bug is very similar to bug #327287. Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
