Thunderbird crashes after showing "ldap domain name mismatch" window

[grandaddyduck]

Binary package hint: thunderbird

Release: Ubuntu 9.04
Thunderbird 2.0.0.21

When typing in an email address into the "To:" bar in the "Compose" window, an error window throws. This says "domain name mismatch error", I guess from the LDAP server I use. Clicking "cancel" or "okay" crashes Thunderbird.

Clicking the "x" in the messagebox corner allows me to continue.
