Unfortunately, the backtrace does not show where it hangs, the backtrace from comment #0 just points to the main event loop. Could you check if this is a duplicate of bug 268038? Bug 268038 comment #27 has some openSUSE specific discussion. If ntrack is not the cause, you probably have to follow http://kdepepo.wordpress.com/2011/05/11/troubleshooting-kded4-bugs/ to find the kded module that causes the issue. If you can provide the information requested in comment #1, please add it. Sorry for the late answer, I've accidentally archived the notification mail. Up to this date I haven't even known that I have ntrack installed, but zypper said so; and the version is the same (014) as in the linked comment you pointed to. Besides, the blog post was really useful; next time I report a bug against kded4, I'll take care. Now, I close this as a duplicate, and if after an ntrack upgrade I can reproduce this, I'll reopen. *** This bug has been marked as a duplicate of bug 26038 *** *** This bug has been marked as a duplicate of bug 268038 *** |
Version: 0.0.1 (using KDE 4.7.0) OS: Linux After starting my machine, kded4 fully uses one of the CPU cores. A little bit after as I attach it to GDB, it moves back to the normal operation.
