Looks like it crashes on exit due to memory corruption. Do the crash timestamps line up with logouts? Please try qdbus-qt5 org.kde.kwalletd5 /MainApplication org.qtproject.Qt.QCoreApplication.exit then start kwalletd5 in valgrind: valgrind kwalletd5 When it started up, use kwalletmanager5 to confirm that it's working and use qdbus-qt5 org.kde.kwalletd5 /MainApplication org.qtproject.Qt.QCoreApplication.exit to cause it to exit. valgrind should have useful complaints.
Hmm... $ qdbus-qt5 org.kde.kwalletd5 /MainApplication org.qtproject.Qt.QCoreApplication.exit Error: org.freedesktop.DBus.Error.UnknownMethod No such method 'exit' in interface 'org.qtproject.Qt.QCoreApplication' at object path '/MainApplication' (signature '')

Logging out does not seem to trigger the crash.
That valgrind report looks harmless, no crash there. Unfortunately there's not much that can be done here until we get a proper valgrind report with a proper error. It would be helpful if you figure out a way to get it to crash more reliably.
(In reply to Vadim Krevs from comment #6) > Logging out does not seem to trigger the crash. Actually, I was wrong. Almost every other logout triggers this crash. Curiously, another user account on the same machine can logout without dumping core. Logging into each user account auto-launches skype, which stores its password in the kwallet but logging out causes a crash only from one user account. I have attempted to rename kwalletd5 and replace it with a shell script that launches the renamed executable under valgrind passing all parameters, etc and redirecting output to a temp file. No more core files (as it usually happens when running things under valgrind obviously) and valgrind logs do not contain anything useful. Fabian - is there anything else you can think of to try to investigate this further?

Not much. Do the various crashes have different backtraces? What the cause of a crash, is it a wild or null pointer? ("p *this" in gdb should show)
