wnck-applet consumes all cpu when using motif applications

[jasonmartens]

I use ssh to redirect my display to my local machine, and run old motif applications from the remote systems on my dapper x server. However, after some amount of time, wnck-applet starts consuming 99% of my cpu, and I need to kill it. After it's killed, a dialog pops up saying: '"Window List" has quit unexpectedly'. I choose reload, and it works fine for a while, but then it happens again, up to three or four times a day.

Thanks for your bug. What version of Ubuntu do you use. Do you have an example of application to run to trigger the issue quickly? Could you get a backtrace when that happens using gdb:
- gdb $(pidof wnck-applet)
(gdb) thread apply all bt

I'm having this problem using Mathematica. I did find a work around. If you use the -noSplashScreen option wnck-applet doesn't spin out of control. I can consistently reproduce this with Mathematica. I'm sure you can duplicate it with the free trial version of Mathematica.

Kenneth, your issue is bug #20412 which is fixed upstream now and should be fixed to dapper next week with GNOME 2.14.1

The product I'm using is GlancePlus from HP. It is non-free and
somewhat expensive, so I doubt that you have access to it. Here is the
backtrace as you requested:

Do you still have that problem in Dapper or Edgy?

[jasonmartens (me-jasonmartens)]

I have not had this problem in dapper for quite a while. I have not
tried edgy.

Marking as fixed for now then. Feel free to reopen if you get the issue again on dapper or edgy
