Bug#621358: kded4 remains runnng after KDE session finished, and loops on the CPU after suspend/resume
Package: kdelibs-bin
Version: 4:4.6.4-1
Some additional remark:
after i attached gdb to the process, made the backtrace, and detached
again, of course the cpu went hi again.
So i attached again and repeated the backtrace: Threads 1 and 3 didn't
move, ie, the backtrace looked identical, but thread 2 did change, so this
one must be the responsible for the hi load.
Below some bt of thread 2, same procedure repeated a few times
(attaching, bt'ing, detaching) (sorry no dgb libs installed, but you get the
idea i hope)
