vlmc remove <snapshot> fails

Hi,

vlmc remove always returns error when removing snapshots.
Here's what I do:

$ vlmc create -s 1024 image1
$ vlmc snapshot image1 snapshot1
Snapshot name: snapshot1
$ vlmc remove snapshot1
vlmc removal failed
$ vlmc close snapshot1
Volume closed 
$ vlmc remove snapshot1
vlmc removal failed

There's nothing relevant in blockerb.log nor blockerm.log.

I'm using archipelago on Debian Wheezy, installed from packages (version 0.4-1~wheezy).
My configuration files aren't modified apart from increasing debug log levels, so file_blocker is used both for blocks and maps.
