I took a quick glance at the backtraces. The first problem looks like Icedove got a piece of mail with an invalid MINE type which is crashing Icedove, which is a bug that should be sent upstream. If you can isolate the email thats causing that crash, that would be vastly helpful. The second one just seems to be that Icedove stalled downloading a large attachment; if you had left it running, it likely would have finished (although I agree a progress bar would have been nice).
Icedove 2.0.0.17 was just uploaded to unstable today, it may fix your issue. If you can test with that version, it would be greatly appreciated. Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
