I checked out xffm from CVS today, the behaviour is still the same.

A backtrace is attached. I haven't looked into that in detail, but in
open_dir *en seems to contain rubbish data: 

(gdb) print *en

$2 = {type = 138879080, subtype = 0, count = 0, st = 0x1f4, tag = 0x4
<Address 0x4 out of bounds>, path = 0x3f <Address 0x3f out of bounds>,
filter = 0x2400 <Address 0x2400 out of bounds>, checksum =
8029744614627868697, load_time = 138805364}

Let me know if you need any more information, I can reproduce this
behaviour on my machine.

Regards,
Jens
