For the record, I have found a way to have the applications work as they

I normally run windowmaker-0.91.0 as my window manager. With this wm,
qt applications freeze.

If I use X11 forwarding with 'ssh -X localhost' and log as myself, I get a
lot of errors in the controlling xterm such as these:

	X Error: BadWindow (invalid Window parameter) 3
	Major opcode:  7
	Minor opcode:  0
	Resource id:  0x49

However, the application is perfectly functional. File/Open in scribus
opens a dialog and does not freeze the application window for example.

If I change the window manager in ~/.xinitrc, I don't need to use the ssh
trick. With KDE's wm or a sole xterm Qt applications run fine.

I am now pretty sure there is something fishy with windowmaker.
