[Qt-interest] qtmutex locked - application waits??

[caius ligarius]

Here you go, this is <200 lines of code. I have stripped out all non-qt
dependencies and left only the basic UI framework along with .ui file.

I have checked this and it compiles (at least on VS2008 which I am using). I
have also attached solution file for you reference.

To reproduce the problem-
Keep selecting random items from the combo-box in the UI (top right hand
side). Eventually the UI will freeze or waits for a few seconds before the
item can be selected. Not sure why this happens?

Thanks,
Caius
