when I killed Konqueror and Amarok, I saw that I had two instances of kded running, each using up almost 100% of my two CPUs.
They had identical stack traces (except for 0x... addresses):

Oops, sorry, didn't realize that I picked a Kopete-specific component. I should also add - it started working fine after killing kded. I upgraded to KDE 4.1 - and it's even worse. I have to kill kded every time I start KDE, and even then, it doesn't always help. Any news on this ? Also, KDE4 doesn't use DCOP but DBUS. You were probably experiencing a different bug. Thanks Marking as NEEDSINF Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed.
