Subject: [sup-talk] [Crash] "thread_by_subject: true" leads to "wrong id
	called on nil"
Message-ID: <1205210652-sup-1364@amethyst>

Hi all,

I am getting frequent sup crashes with "wrong id called on nil" (using the
latest git master), when thread_by_subject is true.

The crash generally happens when the thread index is being built as a result of
a search, or when opening the inbox (which is really just another sort of
search).

I have managed to narrow down one particular crash to two messages sent to the
sup-talk list.  If I set up a new maildir containing only those two messages
and a new sup config, accepting all sup-config defaults and changing
thread_by_subject to true, then I can reproduce the crash reliably.  The second
message References: the first message, although the subjects are dissimilar.

I have attached the two messages, a transcript of my test case session
(including backtrace), and sup-exception-log.txt.  I am not yet familiar enough
with sup or ruby to offer a decent patch; my current fix just hides any thread
which will cause a crash, on line 208 of lib/sup/modes/thread-index-mode.rb in
git master, which is a hopeless workaround really.

Thanks,

Alexandra
