Amarok is bugging udisks-daemon

[Andreas Roth]

Hi,

two or three days ago i noticed that the udisks-daemon is constantly active. 
It takes about 1-5% of CPU. At the same time the dbus-daemon also takes the 
same amount of CPU.
I found out that these daemons are quite active only when amarok is running. 
When i close amarok, the daemon activity returns to normal (nearly zero). I 
also tried to disable all plugins in amarok and disable the 'watch for file 
changes' on the collection scanner.
I've run a strace against the udisks-daemon and writes the following message 
to stderr:
write(2, "\n** (udisks-daemon:2797): WARNING **: Property get or set does not 
have an interface string as first arg\n\n", 106)
The other functions which are repeated are:

What's really strange to me it the response from udisks-daemon telling the 
GetAll method does not exist on org.freedesktop.DBus.Properties. What does 
this mean?
