Bug 187334

If 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?
Also, you need to install the "kdepim-dbg" package
The other issues are reported and being worked on :)
Thanks :)

I'm getting a crash when deleting many emails in an imap account as the original reporter is, however it is when I select many of them and hit shift-delete when they're all selected, rather than hitting delete rapidly.

Backtrace is as follows:
Application: Kontact (kontact), signal SIGSEGV

Server is dovecot imap with maildir storage, although I'm not sure this is a factor given the names of the functions being called in the backtrace.

@Richard Salts: the crash could be different from the original reported here. And as the policy here is one report per crash I need to ask you to file a new bug report containing your backtrace and the information of your configuration. Do not forget to include your KDE4 version and Linux distribution. Thanks a lot!

SVN commit 974322 by stefanek:

Avoid another condition that may cause the threading
cache to become unsorted (and thus cause asserts on
item removal).
