I cleared my error console, restarted Thunderbird, and entered the Address Book. The error console remained empty.
Note that this occurs both with a new "clean" profile, and with existing well-used profiles. The buttons show up in the Calendar, but not in the Address Book. I can confirm the same behavior on WinXP 32-bit, Win7 64-bit, and Ubuntu 10.04 64-bit. -- users@sogo.nu https://inverse.ca/sogo/lists
