Kicker app crashes reliably every time when choosing log off from the KDE menu, with the following backtrace:

Using host libthread_db library "/lib/tls/libthread_db.so.1".
`shared object read from target memory' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]

I have already reported this under as bug #106922 for KDE-3.4.1, and it was said to be due to a bug in KMenuDir and given status RESOLVED, because a bug fix should handle it but did not make it into KDE-3.4.2 release in time.

Obviously, this bug fix did not make it into KDE-3.4.3 either, or the fix is invalid.
I am experiencing just the same old session log-off crashes.
