dbus-daemon consistently maxes out one of my cores (50% usage on a dual-core) according to ksysguard (System Monitor). I researched and found this post
[ubuntu] dbus-daemon gone wild - memory leak - high CPU consumption - Page 2 - Ubuntu Forums](http://ubuntuforums.org/showthread.php?t=1101473&page=2)
where comment #13 said killing kpackagekitsmar fixes this, which I tried and that seems to have fixed it.
On further research I found other posts with this problem, such as
https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/897952
and
https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/896674
and
https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/884701
which suggests to me that a) there can be a variety of causes for dbus-daemon maxing CPU usage and b) this could be a non-distro-specific problem.
This page

and this page
https://bugs.kde.org/show_bug.cgi?id=261180
seem to have identified the issue with kpackagekitsmarticon but seem to indicate it has since been fixed, yet I am still experiencing this issue.
It may be worth mentioning that I am also periodically experiencing problems with npviewer.bin, which I believe is related to flash, maintaining inappropriately high CPU usage. I have no idea if this could cause problems with dbus-daemon. If not it’s a separate issue.
If anyone has any ideas of what to do next, please help me. Is this a problem with OpenSUSE, KDE, dbus-daemon, kpackagekit, or ksysguard? Where should I file a bug report?
