Bug in eventloop handling in KDE's qt-copy (half a day old)

[Joseph Wenninger]

Hi

I think I found a bug in the enterLoop method. I have an application,
which uses excessivly enter_loop, exit_loop, which worked perfect with
Qt 3.0.x, but doesn't work anymore with Qt 3.1 beta X. The application
is quanta in the KDE's cvs reprository.

If I compare the code from Qt 3.0.5 and 3.1 beta, I think (and tested)
that the following patch should fix the problem, and I can't see any
negative side effects.

Kind regards
Joseph Wenninger
