Subject: Update: crash due to fvwm window manager crash
Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: 8bit

Package: xserver-xorg-core


The bug seems not related to xorg but to the fvwm window manager crash. I ran the window manager with gdb and was able to reliably make it crash by some mouse activity.
