Not an isolated bugreport. Daren Russel (on FreeBSD 5.1) reported this
on pan-users:

___________________________________________________________
Hi,
                                                                     
          
Been using pan for a while now, and extremely good it is too, but
there's always a but!) after upgrading to 0.14.1 trying to score an
article fails without exception.
                                                                     
          
Trying to add a score results in: 'Cannot create regular expression:
ANNOUNCE' (or whatever I am using to score the article)  This happens
whether it is the subject, author, reference.
                                                                     
          
The error in the pan log is:
(Null) - Invalid UTF8 string passed to pango_layout_set_text()
                                                                     
          
I tried by renaming the .pan and News/Pan directories, but to no avail.
                                                                     
          
System is FreeBSD 5.1

Ah, then I guess it's common for alle FreeBSD's (and only FreeBSD),
since not anybody else have reported this huge bug. Unfortunately not
a coder myself.

I'm experiencing the same problem:
- Scoring doesn't work
- Adding new scores failed

But I accidentally discovered something really weird.  After building
and installing a new world and/or kernel the scoring works just fine
the first time I start Pan.
Closing Pan and starting it again breaks the scoring again.  I don't
have a clue what may be the cause of this.  But it's very reproduceable.

I'm running FreeBSD Current.
I'll also report this to the FreeBSD Ports-mailinglist.

Interesting information. Will try to make new buildworld and
buildkernel myself to verify this. Will take some time (a week or so)
since I'm currently waiting for a new SDSL line into my home.

If the scoring works up until the point you exit Pan & restart,
what do the contents of ~/News/Score look like before & after
you exit?

I had a hard disk failing on me last week which forced me to reinstall
everything, since then I can't reproduce this anymore :-/
So I'm afraid I can't really help anymore.

On a sidenote, the adding of a Score through the menu's didn't work
after that make kernel & world either, only the coloring of the
articles did.  (Which doesn't anymore now)

I'm not able to add a score, what ever I try.

I'll try to look into this over the next day or two.

I can't duplicate this on Linux -- trying to add a score on `author is',
and the entry showing up in ~/News/Score is analogous to the one in
the screenshot's error message.

Moving to pcre should fix this problem, since pcre doesn't use posix
regcomp().

Marking as fixed as we're now using pcre.

Please re-open if the problem still shows up on bsd.

Great. Any release scheduled?

sure, why not.

Just letting you know Scoring works again.
Thx!
