cannot mount crypto-partitions without sudo

[Allo]

Binary package hint: pmount

> LANG=C pmount sdd6
Internal error: cryptsetup luksOpen failed

> sudo pmount sdd6
works as expected.

This affects me too. I did not have this problem with 9.10. I believe pmount drops root permissions too early:

% pmount -d sdc2
..
spawnv(): executing /sbin/cryptsetup '/sbin/cryptsetup' 'isLuks' '/dev/sdc2'
spawn(): /sbin/cryptsetup terminated with status 0
spawnv(): executing /sbin/cryptsetup '/sbin/cryptsetup' 'luksOpen' '/dev/sdc2' '_dev_sdc2'
spawn(): /sbin/cryptsetup terminated with status 234

% ls -l /usr/bin/pmount
-rwsr-xr-- 1 root plugdev 39K 2009-11-07 18:50 /usr/bin/pmount

% /sbin/cryptsetup luksOpen /dev/sdc2 _dev_sdc2; echo $? # (as non-root user)
234

Also, for me sudo pmount works as expected.

Ps. This /is/ an ubuntu-specific problem. The latest version from git://git.debian.org/pmount/pmount.git works for me.
