Description of Problem:

Crash (Seg fault) attempting to look up contacts
under evo 1.5.5, evo-data-server 0.90, Debian
testing.  Seems to be intermittent.

Steps to reproduce the problem:
1. Start evo
2. Compose new mail
3. enter garbage address up to @ sign (one that is
not in your address book - I used "qwe@")
4. Hit down arrow to initiate autocompletion
5. leave focus of the "To:" field and type some
text in the email.
6. Come back to the "To:" field and initiate
autocompletion by hitting down arrow
7. Repeat 5 and 6 until it segfaults.

Actual Results:

Segfault


Expected Results:

Lookup should fail silently.

How often does this happen? 

Intermittent.  I can get it to happen every
attempt by repeating steps 5 and 6 above for less
than 30 seconds (usually less than 5 times)
