Reproducible: Sometimes

Steps to Reproduce:
Start deleting messages from the inbox folder


Actual Results:  
- works for a small number of e-mails
- at some point the message "cannot move message from folder inbox" appears for each deleted e-mail. The message that is selected after each deletion is not the next message in the folder anymore. Instead the same message is selected every time
- after some more deletions akonadi_mixedmaildir_resource crashes with the above backtrace

Expected Results:  
The message is moved to the trash folder. The next message in the folder is selected.
