Version: (using KDE 4.2.1) Compiler: gcc 4.3.2 20081105 (Red Hat 4.3.2-7) (GCC) OS: Linux Installed from: Fedora RPMs Running Fedora 10 x64 with kde-4.2.1, qt-4.4.3, kmail 1.11.1 from rpm. In kmail, if I do the following, left-click on a mbox folder -> compact folder left-click on same folder -> Mark all messages read none of the new messages are marked as read. If I click on a message in the list, it crashes with the following bug report below. I also tried deleting .folder.index, .folder.index.ids and let kmail re-create it. the same problem. Kmail also complains about utime(FILEPATH,0) failing at startup. I wonder if it has anything to do with NFS-mounted Mail directory. The crash is always consistent with any mbox file, and the smallest mbox file I tried has only one read and one unread message, total 4kbytes. Added info: Even if the folder has only one read message, if I do compact folder, then choose the message, it crashes.

Bug 186940 seens to have a similar backtrace.
SVN commit 980061 by stefanek: Possibly fix the issues with the folder being closed by the compaction jobs (and thus various asserts triggering in the StorageModel code). Not totally sure that all the bugs I'm closing had exactly the same cause (though the backtrace is exactly the same). If you still can reproduce the bug please reopen ONE of these.

This problem also exists for KDE 4.2.4 but the patches above are for KDE 4.3. I have applied them to KDE 4.2.4 with only one line modified in view.cpp and it seems to work. Any plans to port it to KDE-4.2.4 officially so we can convince the distributions to apply the patch? I filed this bug #196763 which should be added to the above list. Thanks
Created attachment 35008 [details] Patch ported to KDE 4.2 branch The original author needs the certify that this is correect!
