Hi, Since I did not get any specific suggestions about this bug, I am attaching another backtrace. Any suggestions for workarounds etc would be appreciated -- should I regenerate the index? Or install a dovecot from the repo where this might be fixed? Is this a known bug? Best, Tamas -------------- next part -------------- A non-text attachment was scrubbed...
