Description William Lovaton 2008-11-13 14:34:04 UTC 
Please describe the problem:
According to powertop file-roller keeps waking up the CPU while doing nothing.  This prevents the CPU from saving power.

Steps to reproduce:
1. Open file-roller (no need to open or create a file)
2. Check powertop



Actual results:
file-roller show up in powertop as the responsible for waking up the CPU 2 times per second.

Expected results:
file-roller shouldn't wakeup the CPU while being idle.

Does this happen every time?
Yes.

Other information:
I am using a Fedora 10 Preview USB Live system, the relevant packages are the following:
kernel-2.6.27.4-68.fc10.i686
gtk2-2.14.4-3.fc10.i386
file-roller-2.24.1-1.fc10.i386

I'll attach a log from strace soon.

strace from file-roller

This shows file-roller polling for something every 0.5 seconds.

Yes, there was a timeout used to check the clipboard.  This is fixed in trunk now, thanks.

Really cool Paolo, thanks!.

Is there any plan to backport this fix to 2.24?
