Application that crashed: kmail Version of the application: 1.12.1 KDE Version: 4.3.1 (KDE 4.3.1) Qt Version: 4.5.2 Operating System: Linux 2.6.31-desktop-2mnb i686 Distribution: "Mandriva Linux 2010.0" What I was doing when the application crashed: Currently testing Mandriva 2010.0 RC1 with KDE 4.3.1 and Kmail 1.12.1 and was able to repeatedly crash Kmail when I created a new folder, then copied an email from my inbox (in maildir format) into my new folder (I called inba which was in mbox format), then attempted to look at the new email in the inba folder, at which point Kmail crashed. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault [KCrash Handler] #6 0x00000001 in ??

Created attachment 37120 [details] this is kde bugreport from crash #2 To be sure, I attempted to reproduce the crash. The 1st crash seen is actually the 3rd crash, this attachment is crash #2.
Created attachment 37121 [details] crash #1 This was the 1st crash produced. To produce the crash, you need to have some emails within your inbox folder. Then create a new folder. My inbox is in maildir format, the new inbox is in mbox format, I named the new inbox with a nonsense name like inba. I then copied an email from my inbox into my inba folder. then I clicked on the email in my inba folder, which then made Kmail crash. This is using Kmail in Mandriva 2010.0 RC1
Unfortunately, the backtrace is not useful. If you can reproduce this bug, please install the debug package for kdepim and paste a better one. More informations on this page: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
This report happened when I pointed towards the "Local Folder" and right clicked to create a new inba folder (as mbox), copied a simple email from inbox (maildir format) by dragging the email to the inba folder and clicking copy. When I clicked on the copied email within the inba folder, kmail crashed. Application: KMail (kmail), signal: Segmentation fault [KCrash Handler] #6 0x0a387380 in ??

This trace produced while inbox was highlighted, and then I pointed to "File->New->Folder" and created a new folder called inbb (mbox format) which was then attached as a subfolder of inbox (maildir format). I then dragged an email from inbox and copied it into inbb. Then I pointed at inbb, highlighted the new and only email present in inbb and clicked the new email which then crashed kmail. These crashes don't appear to happen if these new inboxes already exist with something already in them. If an email already exists before I drag something in, then I am okay. I also notice that the preview panel is empty when I first click on these new inboxes after I have dragged an email into them.

pointed to local folder and created a new folder. Looked in the new folder called inbc (mbox format, empty, preview panel empty) Copied an email from inbox (maildir format) into the new inbcc box, then looked at the inbcc box. Preview panel empty, clicked on the new (and only) email present, and then kmail crashed. This bug seems repeatable. I've added the Kwrite crash as bug 208351. Maybe the crash information within it may help resolve this crash as well as Kwrite's crash too. Application: KMail (kmail), signal: Segmentation fault [KCrash Handler] #6 0x098e9f8c in ??

More information plus crash details filed with the mandriva bugzilla. https://qa.mandriva.com/show_bug.cgi?id=53942 It appears this crash is caused by the preview window - more details starting with comment 5 up to 9 https://qa.mandriva.com/show_bug.cgi?id=53942#c5
Created attachment 37547 [details] crash report with preview window shown below message list This crash report is already attached in https://qa.mandriva.com/show_bug.cgi?id=53942#c5 There are further snapshots taken in 6...9 at above page.
This looks like a dup of bug 180741.
Thanks for pointing-out that bug, but you have several bugs in bug 180741 that may actually be separate problems. Some seem to sound like race-problems where one application looks for info before the other application flushes-out data. This bug creates a segfault and appears only to happen if you enable the preview window, otherwise the problem does not appear to happen. I looked at bug 180741 and I think some of these bugs are related to the preview window: bug 206180, bug 207197, bug 208296, (maybe if there was only 1 message in the trash then also) bug 208314, bug 209008, bug 209704. I'll ask as https://bugs.kde.org/show_bug.cgi?id=180741#c41 hopefully it separates some of those bugs apart.
