Dovecot crashing when attempting to search in virtual folder with fts_squat activated

Hi everyone,

I have now updated to dovecot 2.3.4.1 - unfortunately the issue still 
persists. Can anyone help me figure out if this is due to a 
misconfiguration on my part or another error?

Any help is greatly appreciated!

Cheers
Benjamin
