Hi,

when I go through my daily mails, I usually use the + key to navigate and then press Shift+Del to remove the whole message thread after reading the last mail. Sometimes that action leads to a crash.
After restarting KMail, the first mail from that thread is removed, the rest of the mails is still there. The original message had several direct answers, from which some had larger threads following.

The mails are read over Gmail IMAP.

Here's the backtrace

Anwendung: KMail (kmail), Signal SIGABRT
