It's hard to be sure, but I think this might be the same as bug #13906
which was fixed in 9.4.6.  If updating doesn't resolve it for you, please
resubmit with a more precise description of what's wrong.

Knut replied to the moderation notice to indicate that 9.4.8 fixed the
issue, and asked for a version log.  Here's the git repository:
