Description Nik 2009-05-11 11:04:38 UTC

Version:            (using KDE 4.1.2)
Compiler:          cc 
OS:                Linux
Installed from:    Debian stable Packages

the crash happens if you delete a maessage above a deleted message which is in delete progress.

Here is the setup:
I have a list of lets say 15 mails I want to delete. I now click on the fifth mail. I press ten times the "del" botton, I do this fast and I see the message-"subject" crossed out, but not removed form the message list this fast.
Now I get the crash, if I click at messages above the deleted ones and fast delete them again with "del". In the moment the forth email gets deleted, kmail tries to acces one of the deleted crossed out emails and crashes with SIGSEGV signal 11.
I could reproduce this as often as I want, because after restart of kmail everything is still undeleted and I still have my 15 emails to try it again.

I use the KMail Version 1.10.4
under KDE 4.1.4
I have a german version.

This is my very first bug report. But I hope I did mentioned the important facts.

Thanks for reporting! :)
As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? It will be useful to identify the crash cause.
Thanks!

Comment 2 Christophe Marin 2009-05-23 15:52:59 UTC

Changing the bug status until we get a backtrace (comment #1)

Comment 3 Kamil Neczaj 2009-05-25 18:57:16 UTC

confirming. I have kdemod in archlinux. There are additional packages with debuging symbols. 
I have something like this without the package with debuging symbols installed:
