Mutt is accessing a maildir directory with a several subdirectories
directly. All of them are added as mailboxes so I can jump to unread
mails. During startup and folder changing mutt is accessing all the
mailboxes.

I noticed that as well.
During the last days memory usage was not that high so maybe this
is the reason why I did not see any errors. I will continue running 
latest git and see if a get the errors again when more memory is being
used.

Kind regards,
