error message at boot "udev-event: unable to create db file [...]

Binary package hint: udev

I'm using dm-crypt / cryptsetup an up-to-date Feisty installation.

After the latest upgrade, there is an error message displayed at boot after I type in the passphrase for the first "early crypto disc" (/etc/init.d/cryptdiscs-early).

The message says:
"udevd-event[2492]: udev_db_add_device: unable to create db file '/dev/.udev/db/block@dm-0': No such file or directory"

When I cd to the directory "/dev/.udev/db/", "ls -l block@dm-0" shows: "/dev/.udev/db/block@dm-0 -> mapper/sdata"

The subdirectory "/dev/.udev/db/mapper" to which the symlink points doesn't exist.

Who/which process/script/package creates that directory? Are there some udev-rules broken in the latest package?
If I create the directory "/dev/.udev/db/mapper" manually, it disappears after a reboot.

Just annother observation:

When I issue the cryptsetup command like this: "cryptsetup luksDelKey /dev/sda1 5"
(to erase keyslot no. 5), the program asks for "any remaining LUKS passphrase".

When I type in a correct passphrase, the command works as expected (although slower than before the latest upgrade). But when I provide a wrong passphrase, the following error message appears which seems related to the issue:

"Warning: /dev/.static/dev/mapper/temporary-cryptsetup-9322,rendezvous: wait for udev processing timed out"

OK, today's upgrade fixed this.
