I had to remove ~/.icedove and let it recreate a new account from IMAP to get it back running. Activity manager showed before trying to reindex a folder and than it freezed to dead. Removing the folder_file and the folder.mfs did not resolve it.
So you may reduce the severity of this bug as the crashed indexing can be fixed due recreation of the IMAP account on the client. Nevertheless main issue here is still present with a new created account. Selecting a lot of (very small txt) messages (46xxx in my case) in a IMAP folder with Ctrl+A results in 100% CPU (1 of 2 Core) and Icedove not responding anymore: PID PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4892 20 0 761m 406m 23m R 100 20.1 3:22.40 icedove-bin Best regards, Jan -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
