Mutt losing folders with new mails

[Sebastian Stein]

Hi,


I'm using the typical

POP3 -> fetchmail -> procmail -> mutt

chain on Kubuntu 19.10 with mutt 1.10.1.

In the past weeks (probably after upgrading to Kubuntu 19.10) I noticed that
mutt forgets about folders containing new mails as soon as I change one
folder.

For example, while mutt is running:

- I fetch latest emails
- mutt shows 3 folders with new mails
- I change to first folder with new mails
- mutt shows correctly 2 more folders with new mails
- in folder, I delete new mail or move it to different folder
- mutt forgets about 2 other folders

Has anyone else noticed that? What could be the reason? Is this file system
specific? Where does mutt store information about folders with new files (in
memory or some temporary file)?

Best regards,
Sebastian
