            Bug ID: 392296
           Summary: Crash when dragged after setting a bookmark
           Product: marble
           Version: unspecified
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: marble-bugs at kde.org
          Reporter: nuorama at gmail.com
  Target Milestone: ---

Application: marble (2.2.20 (2.3 development version))

Qt Version: 5.9.2
Frameworks Version: 5.44.0
Operating System: Linux 4.16.0-rc6-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:
Set a bookmark then immediately dragged the map (left mouse). Did not manage to
reproduce the crash, but I have seen crashes with a similar stack before.

The crash does not seem to be reproducible.
