            Bug ID: 431539
           Summary: Kmail crash after configuring Expire on a folder
           Product: kmail2
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: bingmybong at btinternet.com
  Target Milestone: ---

Application: kmail (5.16.1 (20.12.0))

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.10.5-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
1. I selected a folder, 
2. Created an expire (via Folder Properties)to happen on that folder after 365
days and transfer messages to wastebin 
3. Pressed "save settings and expire now" - the button didn't grey out to show
it was working even though it was working fine (progress message says "trash"
and not "wastebin")
4. After all messages transferred to wastebin, i selected another folder.
5. The new folder emails were displayed above the message pane.
6. I selected an email to read and the message pane got the "Retrieving
messages..." 
7.  It sat there "retrieving" for ages and eventually crashed.
This happened twice in a row.

The crash can be reproduced every time.

-- Backtrace:
