desktopcouch-service hangs with 100% cpu

[Frans Slothouber]

Binary package hint: desktopcouch

This happens shortly after I log in.
I let it run for 20 minutes or so, but it keeps staying at 100% cpu.

This is with an up-to-date lucid beta1

Same problem here. I have to kill the process manually.
strace reveals it's polling all the time (while I guess it should just wait for events)

{{{

This is not related to samba as I have no connectivity issues on my samba share. The only connectivity issue I'm having is the one listed here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759997 and it's related to my atheros wirlesss card.

I never had this problem with lucid or maverick however on natty I get this shortly after login:
