In a folder of mine I've got some mails that doesn't thread. It's pretty weird. 
All the other mails thread just not these 3 mails. I'll attach a screenshot.

The subject of the mails that doesn't thread is:
[Bug 104841] Getting "02 I can't get your name.  Goodbye."

could it be because of the ' in the subject? I'me not sure how mozilla is 
determaning to thread a message or not

Is the threading saved somewhere? Like in the msf file? Or is it done on-the-fly
when opening a folder?

threading is saved in the .msf file. We thread by subject for mail folders but
not for newsgroups. Is this a mail folder? This works fine for me, so I can't
reproduce it. If you move away your .msf file, are the messages threaded
together correctly?

when I deleted the msf file it threaded ok. I'm attaching the corrupted msf 
file. The problems subject was:
"Custome header" filter not working if rules.dat is copied

is there a checkmsf file util that can detect corrupted msf files? Or how do I 
detect corrupted msf files?

I was not suggesting that the .msf file was corrupt, just that the threading was
wrong. To figure this out, we'd need a reproducible case, i.e., one where
deleting the .msf file and regenerating it would exhibit the same bug. I can
look at the .msf file but I doubt that it's corrupt.

We're doing a general bug cleanup... anything to add about resolving this bug?

I believe this is a problem with mork, and/or the way we do subject threading.
I've seen this happen in the debugger a few times. What seems to happen is if
you delete all the messages in a thread, and then get a new message with the
same subject as the message(s) in the thread, and then get a second message with
the same subject, we think the second message belongs in a thread by itself
because there's a phantom thread object returned by the FindRow call in
nsMsgDatabase::GetThreadForSubject(nsCString &subject). FindRow can only be
called if the column you're searching on is unique in the row space. It is, but
I suspect that having the empty thread causes problems somehow. This is all to
say why deleting the .msf file fixes the problem, because the empty thread is
deleted with the .msf file. I'll look into finding a reproducible case and see
if I can figure out what's going on.
