gvfsd-smb uses all cpu when trying to connect to samba share

[stop]

Binary package hint: samba

When I try to connect to a samba share (via typing in the nautilus location bar: smb://servername/sharename) I get an endless hourglass and maximum cpu usage of the gvfsd-smb process.
The connection is not possible.
This used to work before.

I can confirm this on my x64 Ubuntu 10.10. This weekend (Sep 04. and 05.) it still worked. But now it seems broken.
