Hi,

It is indeed an imap/gmail search. I apparently have ~90kMail in there
(wow, I thought it would be more), but for any given search I expect
anywhere between 50--500 hits.

I search for one or a couple of words, no ifs, buts, ANDs, or ORs. For
example:

"george harris montmorency"
"three men boat"
"jerome"

Normally during a search, the minibuffer first says

Searching [Gmail]/All Mail...

to which it eventually attaches a "done". After this, I get asked
how many mails to retrieve if there are more than 200 hits. The crash
occurs before the "done".

/Mikael
