I thought this was fixed already, but I guess not. It would be helpful if you could either

a) Enable debug symbols so the backtrace would show exactly where it crashes

and/or

b) Send me the user's dovecot.index* files so I can try to reproduce the crash. (The .cache file may contain some cached headers and such, so might be problematic.) This probably isn't INBOX but some other folder that crashes.

Anyway, the problem is that the dovecot.index.cache file is somewhat broken. Deleting it will fix the crashes.
