nmail: [Bug] Crash after some time in the list view, with no user action

Sorry if you are hearing so much from me lately. 😮

I’ve set up my work email account and nmail manages to fetch a handful of messages (some in the Trash, and everything else is in “Deleted items” because I have a forward/delete procedure in place), but every time I try to fetch e-mails from this latter folder, nmail crashes with the following output:

unexpected termination: 13

Here is the log file: log.txt

It may be worth noting that there are several thousand messages in this folder. The white space in “Deleted items” does not seem to be the issue because nmail successfully fetched like 10 or 12 messages from this folder.

Note also that the account was initially set in French in OWA, with folder names translated to French. The associated accents could not be displayed properly in nmail (I had some broken syntax instead), which is why I changed the region to English in case this was causing the fetching problem, but it turned out that it was not the issue.
