Possible duplicates by query: bug 292569, bug 285747. Reported using DrKonqi
The second trace is a dupe of bug #285747 The first one is in the same area, but this: #7 0xb5f1b360 in vtable for QPixmap () from *usually* means an ABI incompatibility - could however be just a corrupted stack as well. With all other reports i'd assume a stack corruption, probably some QList/QMap invalidation. => If you get more crashes that end in some "vtable" notice, that's interesting. Otherwise this is just a dupe.
first trace is dupe of bug #290482 - still they're both likely the same issue *** This bug has been marked as a duplicate of bug 290482 ***
