This attached exception log was generated after sending a reply,
before the inbox buffer was redisplayed.
I have the following small modifications to 99e62d55 included (still
required for importing to xapian in my case):
--snip--
- raise ArgumentError, "expecting a symbol" unless t.is_a? Symbol
+ t = t.intern if t.is_a? String
+
+ unless t.is_a? Symbol
+ m = "expecting a symbol, got a #{t.class} (#{t.to_s})"
+ raise ArgumentError, m
+ end
+
--snip--
Thanks

I'm guessing you're using the Chert Xapian backend. When I moved all the
index data into Xapian it started triggering this Chert bug.
Unfortunately, it's nondeterministic and very hard to reproduce in a
small testcase. I've been holding off filing a bug upstream until I had
a better failing testcase than "run sup-sync". If anyone would like to
familiarize themselves with the xapian-index internals and narrow this
bug down a bit I'd be very glad for the help.
The Flint Xapian backend seems to work fine, so for now I suggest using that.

Your guess is as good as mine here...I didn't realize there were
different back ends. How would I go about switching?
Thanks

Interesting, AFAIK Flint is still the default. Check for a
.sup/xapian/iamchert file to see if it's really a Chert DB. If it is
Chert, you'll have to delete the xapian directory before you can switch
to Flint. The environment variable XAPIAN_PREFER_CHERT controls which
backend is used. Set it to the empty string to make sure you're getting
Flint.

Nope. I've got ~/.sup/xapian/iamflint though...
Thanks for the info.

Well, that's not good. How often does this bug occur? What version of
Xapian are you running? How many messages are in your index?

It's only occurred twice, but both were with my polluted index of ~77k
messages. Let me run for a bit now that I've cleaned out my string
labels and see what happens.
Thanks
