Bug 75280 – Sometimes when restarting Xorg, pypanel 2.0 eats 100% cpu

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Joseph Garvin 2004-12-22 00:32:37 UTC]

Sometimes when I press ctrl+alt+backspace to restart Xorg, gkrellm2 takes an extremely long time to launch. Investigating why, I ran top and discovered that whenever this happened it was because pypanel 2.0 was eating 99-100% of my cpu. I have first pypanel and then gkrellm2 startup in my .xsession. This only seems to happen after restarting Xorg.

Reproducible: Sometimes
Steps to Reproduce:
1. Have pypanel open on startup of Xorg, by placing in .xsession
2. Restart the server
3. Run top and see if pypanel is using most of the cpu

Actual Results:  
PyPanel was eating 99-100% of the cpu

Expected Results:  
Used a normal amount of cpu.

My .xsession file:

Compiled with GCC 3.4, although I am reasonably sure I have this problem even
when I had compiled with GCC 3.3.

The last time this happened I had restarted Xorg because a SDL game froze. I
play alot of SDL games, so there might be some correlation between this and
pypanel screwing up. It's a road to try if you can't identify anything else =)

My gut feeling is that this is not a problem with Gentoo or our ebuild for 
pypanel, but rather an upstream problem.

Try sending off an e-mail to the pypanel developers about this. Hopefully they
know what it might be, and may even have a workaround.

If you learn something useful, please reopen this bug with relevant info, so that
I may update the ebuild to fix this.
