Ok, I've done it and the last call in a KDE lib was the one at line 237 in
kmessagebox.cpp (int result = guardedDialog->exec();). As I had a QT without
debug info, and the other calls in the stack were QT related, I've rebuild QT
with -debug. Now I cannot reproduce it and I don't have the old BT.  :-( It
happened once when running the app outside of gdb, but I couldn't get it when
I run inside the debugger.

Does the above help? (I doubt it does).

Well, one more try before sending the mail and here it is:
