Also you have mentioned something like "Qt was compiled with Visual Studio 2005, but I use VS 2008". You also indicated that you recompiled Qt (with VS 2008?). Really double-check that you compile ALL your DLLs your application links against are compiled with the SAME compiler and even the SAME compiler SETTINGS (that also goes for the *.exe itself off course).

This is because when you mix e.g. the "runtime environment" (debug vs. release, shared vs. non-shared etc.) your application possibly pulls in different C++ runtimes, giving weird runtime effects such as the one you could be observing. Not to mention that the shipped C++ runtimes from VS 2005 and 2008 are different...

Cheers, Oliver
