            Bug ID: 347745
           Summary: kmail crash while removing folder
           Product: kmail2
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: richard at ytivarg.com

Application: kmail (4.14.6)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
1. opened kmail
2. selected not-quite-empty directory
3. selected "delete"

"Are you sure" dialog appeared, and before I could respond it was replaced by
the crash reporter.

This particular folder was imported as part of a kmail archive from a different
computer.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
