Re: [STUMP] Stumpwm Crashes when disconnecting monitor via xrandr.

[David Bjergaard]

Can someone summarize the state of this bug? I have very little time to
dig into this, and I have no way of reproducing it on my machines.  I
know that there was some references to previous patches to address
this.  That would at least localize this bug to some region of the code.
