The KDE Gardening Team selected the December “Bug of the Month”.
It is Bug 288410: KDE daemon kded4 crashes on wake up (related to power/battery change)
Reasons for the nomination:
- the bug is one of the most reported crashes in our bug tracker,
- a defunct kded4 process can cause several other issues,
- it is annoying to restart the desktop just after a wake up,
- getting a crash dialog when the laptop wakes up makes bad publicity,
- it might be fixable, it looks like an access to a stale object pointer.
If you are able to fix it, you will receive a honorable mention in the next issue of my blog post “The Bug of the Month” on Planet KDE.
Not all developers that would be able to fix it are subscribed to this bug. If you know someone, feel free to point him here.

I would start with marking it as confirmed…
d&r
As there is no honorable mention for November: does it mean the bug didn’t get fixed?
Thomas, we can mark it as “confirmed”, if we have confirmation, where the bug is. It could be in KDE code, or upstream in udev/upower code, e.g. notifying us about devices that no longer exist.
Martin, I had hoped we find a fix before the next monthly bug is announced. If a bug needs more time, there is no need to resign 🙂
But to answer your question, we have two potential fixes, and a decision needs to be made if either of them can be applied. If you are affected, help testing the patches referenced from the Gardening page.
