It's purely an internal crash in Qt4 about memory allocation. It's not digiKam stuff... Gilles Caulier
Same backtrace in fact than #299886 *** This bug has been marked as a duplicate of bug 299886 ***
I fail to see how it is the same backtrace. Anyway, in both of them the issue is memory corruption. Needs a valgrind trace to find out where it happens.
