bfs-tools/recover crashes

[Anarchos]

When running recover with

recover -dv /dev/disks/scsi/0/0/0/3_4 /Data2/recovered

It crashes after displaying "Checking disk structure integrity" (or something like that) and "1050 nodes".
Below is the gdb session i could do, extracting some informations.
Crash is reproducible.
