Bug 246112

Application: kontact (4.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
When deleting several emails and the connection is slower, the emails to be deleted will be disabled (greyed out) before they are actually deleted from the IMAP server and then synchronized/taken off the local email list. When kmail is busy doing its deletion sync with the IMAP server, it is very fragile. If one does not wait until it is finished but clicks on one of the greyed out messages and/or tries to delete more messages, KMail crashes with a seg fault.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
