I have for some reason not seen the error since applying the above 
patch. But wouldn't it make sense to include the patch in the stable 
release so others can give input in the rare case they experience the 
same issue? At least until the issue has been resolved.

I don't say that this is a Dovecot issue, and I admit that it have to be 
a rare case, but when two independent people experience the same error, 
there have to be a problem somewhere.
