There was no fix, the bug was accidentally closed. So far I've 
not been able to replicate the bug.

hi,

we've had a report about this in the debian bug tracking system:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=399924

and possibly

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401525

the bug report says that it's been fixed in CVS, but then there's a
rather ambiguous "still  need to look into this" message afterwards and
the bug is still in state: assigned.

as debian will be freezing really, really soon if there's a fix for
this i'd really like to see it so i can backport it to the 5.2.0
packages that are going to ship with the next stable release.

thanks!
