            Bug ID: 377574
           Summary: Crash from segmentation fault when importing multiple
                    clips of different framerate
           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: lintz89 at gmail.com
  Target Milestone: ---

Application: kdenlive (16.12.3)

Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:


I did import multiple clips when having the standard 1080p 25 fps. When I then
imported 4 clips from same source camera with 1080p 30 fps. The program crashed
upon the question to change framerate on project.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
