Thanks for not forgetting this :) I'll try out the patch first thing 
tomorrow.

What I initially wanted to achieve was to have some folders (such as 
Sent, Drafts, Trash and INBOX/Spam) that the user wouldn't be able to 
delete, but creating subfolders would be allowed. The ACL setting of 
"owner lrwstipek" should do that, if I'm not mistaken.

I had more plans of setting ACLs on other folders such as Public/Spam 
and Public/Ham (no deletion, no subfolders), however, I am not sure 
anymore if ACLs are really the way to go. I've had a hard time getting 
them right, as I described in [1] and [2]. But that's unrelated to this 
crash issue.

I'll report back ASAP after applying the patch.

Thanks again, 

Andreas
