When debugging it's sometime useful to have two similar situations, one that works and one that fails.
We have that here. Two machines : * same brand (Asus) but not same model * affected one is Ubuntu 12.04, working one is Ubuntu 14.04 * same WiFi network * same Thunderbird version (from their regular Ubuntu packages, details below) * accessing same IMAP provider, same IMAP account * nothing changed recently on either (only location and thus wifi changed yesterday) * working one has a thundebird profile with 9 "mail servers", failing one has 2 (including "local folders"). * one crashes when connecting to IMAP, one works. Any hint appreciated. Thank you for your attention.
