Vanilla x86_64 thunderbird (thunderbird-1.5-0.5.1.rc1) (installed a week
ago when evo started dying on no ascii folders), only extension : enigmail
0.93.1 (not that it actually works)

Rawhide killed evo a week ago (#174931)
It killed thunderbird today
I'm running out of imap clients. I still have squirrelmail, and it's not
even the rawhide one, since that one started misbehaving at least a month
before (#162852)

Do you want a bug entry for this problem too ?
