This bug is grave (I've adjusted its severity accordingly). It breaks unrelated packages entirely.
I have this problem too. The failure mode is quite cryptic. Killing udisks-daemon is the only way to fix it, though I have not tried the patch attached to #592719. Since this is grave, I suggest that the maintainers try the patch which was attached to #592719 three months ago. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
