Comment 4 for bug 108650

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.
