Bug#353453: gnome-panel: When using Mathematica-5.1 from remote server, wnck-applet causes heavy CPU load

[Tamas K Papp]

Package: gnome-panel
Version: 2.12.2-3
Severity: normal


I am using Mathematica-5.1 from a remote machine (via ssh -Y).  When I
start the client program on the remote machine, it works nicely using
my X server, but wnck-applet grabs almost 100% of the CPU.  Just to
clarify: the only remote application is mathematica, everything else,
including wnck-applet, runs on my desktop.

killall wnck-applet solves the problem (dialogs for restarting Show
Desktop, Windows List and Window Selector appear and I reload all
three) and wnck-applet behaves well from then on.

This problem does not appear with other remote applications (I tested
xclock, xcalc and they don't cause any problems).  

.xsession-errors shows:

/etc/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/gdm/PreSession/Default: running: /usr/bin/X11/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/lib/gdm/:0.Xservers" -h "" -l ":0" "tpapp"

Nothing appers in .xsession-errors after I start mathematica or kill
wnck-applet.
