Strange behaviour of QFileDialog::getSaveFileName

[LuckyBlade]

Hey guys,
I'm facing an strange error when opening an savefile-dialog with QFileDialog::getSaveFileName.

If I want to debug my application the error
"NtClose was called for a Handle that was protected from closing via NtSetInformationObject" (quick translation by myself from german into english) appears when reaching the line with QFileDialog::getSaveFileName.

But if I just start the application (without the debugger attached to it) it all runs well...QFileDialog::getSaveFileName gets called correctly and without any errors and I can select a path where I want to save my files.

Anyone else did face that problem? I want to debug my application because there are several bugs in it but I can't because of this strange behaviour :-/

Thanks in advance for an answer.

BTW: I'm using Visual Studio 2008 and Qt 4.1

Maybe you have a bug somewhere which is corrupting the heap or stack and thus causing this error?

I figured it out.
The reason for the errormessages was my antivirus program "Avira Antivir".
This is the workaround link for german people:

and a quick translation for you other guys
After an update of the virusscanner visual studio couldn't load the wininet.dll if the debugger got attached.
The only working workaround is to deinstall the Avira Guard/MailGuard/WebGuard/Rootkit-Protection and do a reboot.
