Crash when moving thru mail query results

[humdinger]

This is alpha4.1

I've seen the following crash 3 times out of 5, but it's not 100% reproducible:

• Query for new mail.
• In the result window, filter for some string (with activated type-ahead filtering in Tracker).
• Open a mail in Mail.
• In Mail go to the next mail and trash it.
• Move to next or previous mail (I'm not sure what I did exactly, I think navigating a bit thru next/prev mails does the trick...)

--> crash.

Twice I got this:

And once this one:

[anevilyak]

Might be a missing bit somewhere in the typeahead filtering implementation, unless it's reproducible without it as well.

[humdinger]

I've now played around some more, and it looks like the type-ahead filtering is essential to get it to crash.

[humdinger]

Cannot reproduce any longer. Fixed, I suppose.
