Bug#737915: xnest: segv on mouse entering second nest screen
Package: xnest
Version: 2:1.14.5-1
Severity: normal
File: /usr/bin/Xnest
If Xnest is run with two screens then when the mouse pointer is moved
into the second screen it dies with a segfault. Eg.
Xnest -scrns 2 :1
move mouse into second screen
=>
segv
If the mouse is already in the second screen window then move out and
then back in to provoke the problem.
