Excessive CPU load in settings window

[Lars Ljung]

Binary package hint: xchat-gnome

When the settings dialog window is open xchat-gnome and Xorg is using about 40% CPU each. When I close the settings window everything goes back to normal. It's not crashing.

When using strace I get this when opening the settings window (most of it cut out):

Which versions of Ubuntu and Xchat are you using?

[Lars Ljung (larslj)]

Sorry, Feisty and xchat-gnome 0.16-ubuntu3.

[Sebastien Bacher (seb128)]

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Lars Ljung (larslj)]

No backtrace available since the program doesn't actually crash (except when using strace, but forget about that)

I cleared all gconf settings for xchat-gnome and the problem disappeared. But when I set a background image the problem returns, even if I disable the use of the background image. This is reproducible on my system.

Once you have tried to use a background image there is only one way to solve the problem, that is to clear the value of /apps/xchat/main_window/background_image using gconf-editor. When you clear the value the CPU usage immediately drops. I tried it with png and gif images, not sure if it matters though.

Is this still an issue for you? May you please try to reproduce it with Gutsy? you can grab a CD Image from here: http://www.ubuntu.com/testing/ thanks in advance.

[Lars Ljung (larslj)]

Just tried it on Gutsy and I can't reproduce it there, so I guess you can close this bug.

[Sebastien Bacher (seb128)]

closing the bug then, feel free to reopen if you get the issue again with the new version though

[Andrea Corbellini (andrea.corbellini)]

I reopen this bug since I get the preferences window eats 100% of my CPU.
I'm using Ubuntu Hardy with xchat-gnome version 1:0.18-2ubuntu1.

[Sebastien Bacher (seb128)]

don't reopen issues closed for months only because you have a similar bug, open a new one rather
