I could reproduce it. I didn't look into what the problem was in detail, but KMail::MessageProperty::filtering () is dereferencing an invalid pointer. So, thinking that it is a problem with the Command scheduling code, I am increasing the severity. Onur, that's a classic KMail problem you're seeing there. I'd probably best explain that on IRC sometimes, it's a bit complicated. In a sentence: we don't have message pointer refcounting, only something approaching it, badly, called getMsg/unGetMsg, which leads to frequent message pointer invalidation. *** Bug 136801 has been marked as a duplicate of this bug. *** *** Bug 122029 has been marked as a duplicate of this bug. *** *** Bug 148412 has been marked as a duplicate of this bug. *** Can somebody confirm this on a recent kmail version? |
Version: 1.9.1 (using KDE 3.5.1, Kubuntu Package 4:3.5.1-0ubuntu7 dapper) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.15-17-686 I selected all mails (~90) in my SPAM folder and pressed the "mark as spam" button in the toolbar. While KMail was doing the filtering, I select all mails in this folder (CTRL+A) and pressed Shift+del and confirmed the deletion. Then it crashed. This seems to be a race-condition or locking issue of some kind. Backtrace follows: (no debugging symbols found) Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
