[Qt-interest] Show QT source in QTCreator (and strange deadlocks)

[Ori Lahav]

Hello QTers,
I'm getting some mysterious deadlocks while running my application. The
stack trace shows the deadlock is in QT, but QTCreator shows the disassembly
instead of source code, so I can't debug it.
What should I do to make QTCreator show the source?

Thanks,
Ori.

P.S.
If anyone can see the problem just by viewing the stack trace, here it is:
