Your dovecot.index.cache file is probably broken somehow. Try moving
dovecot.index* files elsewhere and see if it works then? If it does and
dovecot.index.cache doesn't contain anything too sensitive
(subjects/from/to addresses), could you send me the dovecot.index*
files?

If it crashes even without dovecot.index* files then the mails
themselves contain a broken message. It would help if I could get that
message.

Unfortunately this backtrace is almost completely broken and it doesn't
really help.. You also could try compiling Dovecot itself with debug
symbols and getting backtrace from it. That'd probably work.
