            Bug ID: 334779
           Summary: KNotes crashes Kontact
    Classification: Unclassified
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: twtroughton at gmail.com

Application: kontact (4.13.1)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic i686
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
I had two collections selected in KNotes. One was supposed to be the default
collections. I created a note, which appeared twice. Edited one note - entered
message. When I edited the second note with a different message, I got a
dialogue box asking me to compare and choose one. I selected one, then deleted
the other. Went to KNotes Settings, collections, and unselected the not default
collection. Kontact crashed.

Other notes - There is nothing in my .kde/share/apps/knotes directory except a
print folder.

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