Version: (using KDE 4.0.0) Compiler: gcc 4.1.2 OS: Linux Even though this is not a crash per se, it is pretty serious since the whole desktop freezes. How it happens: After customizing desktop fonts (by invoking systemsettings, "Appearance" in the Look and Feel area), and applying changes either by pressing OK or Apply, the system stops responding. Buttons and windows become totally non-responsive, and this includes the panel and elements within it. The keyboard remains functional, however, and one can get to the virtual ttys by the usual method of pressing Ctrl-Alt-Fnkey. Examination with top (after switching to a text console) reveals that kwin is using 96% of the CPU. Killing kwin restores responsiveness in the desktop, but it becomes unusable since kwin is not running and no application can be launched. However, a clean log out is possible. Thanks for any help into this matter. Regards, Eduardo Sánchez Member, KDE-ES Spanish l10n team
It seems that the bug reporter did not get my details right. I am using Slackware 12.0, gcc-4.1.2, with KDE 4.0.0 compiled from released sources. My PC is a 450MHz PIII with 256 MB RAM.
I cannot reproduce. After the lockup happens, can you attach gdb to kwin and provide the backtrace? (http://techbase.kde.org/index.php?title=Development/Tutorials/Debugging/How_to_create_useful_crash_reports)
Waiting for a response.
Shortly after filing this bug, I was unable to use Internet or GNU/Linux for a long time. Right now I reverted to KDE 3.5.9 so I request this bug to be kept as closed because I could not reproduce it. Thanks Lubos and sorry for all this effort. Regards, Eduardo
