QFileDialog::getOpenFileName() gets stucked

[elcuco]

Ok, this is wierd, but some application which works PERFECTLY on Linux, does not run on win32. The linux system is OpenSUSE 10 qt-rsync, and on Windows it's mingw4 on XP Qt 4.1.0 (from the released binaries).

The code which gets stucked is:

QString s = "Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)";
	QString s1 = QFileDialog::getOpenFileName(
                    NULL,
                    "Choose a scanned (300dpi) image",
                    "",
                    s );
 
	if (s1.isEmpty())
		return;

QString s = "Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)";
	QString s1 = QFileDialog::getOpenFileName(
                    NULL,
                    "Choose a scanned (300dpi) image",
                    "",
                    s );
    
	if (s1.isEmpty())
		return;

To copy to clipboard, switch view to plain text mode 

When I choose a file in the getOpenFileName, the application gets stucked. If I cancel, it works. The same code on a save functions works. Copying the code from the save routine gets the same effect (applicatino gets stucked).

Any ideas how to debug such thing?
