            Bug ID: 355945
           Summary: Lancelot crash when trying to add a program to
                    favourites
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: vicke569 at gmail.com

Application: lancelot (1.9.5)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.2 (jessie)

-- Information about the crash:
- What I was doing when the application crashed: trying to add iceweasel to the
favourites in Lancelot

- Unusual behavior I noticed: the Lancelot menu could not be opened after a few
tries to add iceweasel to the favourites

The crash can be reproduced every time.

-- Backtrace:
