[Pkg-xfce-devel] Bug#564694: Bug#564694: xfdesktop4: Crash when moving desktop icons on secondary screen

[S. Raase]

Hello,

Tell me of a driver which can product two X screens on one server and 
I'll try. I've just never seen some other driver for hardware I posess.

grep "install xf" /var/log/dpkg.log* [after gunzip] tells me:
xfce-keyboard-shortcuts in November, xfce4-clipman in October. A few 
more in September. Nothing affecting X11 since November.

I attached three sessions with gdb, but it didn't work.
First one is complete, the others look the same in the beginning.

Which dbg-packages do I actually need? I only installed xfdesktop4-dbg.
