I Was filtering a various mail thread (with unread and read message) to move them in a dimap subdirectory of my mailbox.

There may have been race condition with auto-fetch of messages ?

This bug happenned 4 time in a row (not on the same messages each time).

From bug 253164:
-- Information about the crash:
I was moving a thread of messages I'd accidentally deleted back to a DIMAP
folder from the local trash when I got the crash.
kmail process was still active, but no U/I.  I had to kill -9 the process to
get it to go away.
After restarting kmail, the messages were moved successfully, so the crash was
after the move.

This looks very much like the QTreeView crash I just fixed in Qt.
http://bugreports.qt.nokia.com/browse/QTBUG-16292


For bug triagers: any crash inside QTreeView::indexRowSizeHint where it uses a deleted index (so it could crash in either index.row() or index.parent() like here).

[Comment from a bug triager]
Other mass crashes with the same functions involved: bug 257336, bug 223245.

@David: should this report be closed as UPSTREAM ? or only when the Qt issue is fixed and closed ?

KMail crashed twice while deleting several mail with the "canc" key. I think it will do it again if i repeat the action, despite the bug being tagged as "solved".
Thank you for your help!

Tried to recreate the bug: deleting several unread messages always makes KMail crash.
I'm using Kubuntu Lucid Lynx LTS
Comment 31 Christophe Marin 2011-05-08 02:31:23 UTC 
your backtrace mentions 'Qt Version: 4.6.2'

Note that the fix is in Qt 4.7.3

Will the fix be in the LTS as well?
Thanks for your great job! (and sorry if the question is stupid)
Comment 33 Christophe Marin 2011-05-10 10:20:13 UTC 
ah, correction, the bug is marked as fixed in Qt 4.7.4

You can ask your distribution to backport the fix to their current Qt package. Just ask them to read http://bugreports.qt.nokia.com/browse/QTBUG-16292

(note, Opensuse already has it)
