[Bug 1282119] [NEW] udisks-daemon randomly uses 100% CPU

Public bug reported:
Ever since i freshly installed Kubuntu 13.10, some hours after system
boot the udisks-daemon starts to use 100% of the CPU.
The symptoms are similar to this debian bug: https://bugs.debian.org
/cgi-bin/bugreport.cgi?bug=728798
Usually i also just kill the daemon, but this problem persists after every reboot. Due to the random nature of the problem it's somewhat hard to debug and to know what information is helpful.
I usually just write some code or documentation and doesn't insert any new media, devices, cables, etc.
strace shows, that it is polling in a tight loop:
