--- Comment #4 from Christian Saemann <christian.saem...@gmx.de> --- In case this helps: I've just had to clear the cache of a folder once more, so this still happens in 16.12.2. It seems to be connected to filtering: the folder contains newsletters, which are put there by a filter rule upon receipt. I can't see anything special about the filter I use, though. -- You are receiving this mail because: You are the assignee for the bug.
