            Bug ID: 362997
           Summary: Kdenlive crashes on startup
           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: jacob at nerdonthestreet.com

Application: kdenlive (16.07.70)

Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.5.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

After installing updates recently, I'm unable to open Kdenlive. When I try to
launch it, I get an empty window frame, which freezes for a few seconds before
crashing.

This started happening with Kdenlive 16.04.1-1 from the Arch "extra"
repository. Since then, I uninstalled that version and installed the latest
version of the "kdenlive-git" package in the AUR, and it's also experiencing
the problem. An old 15.04.3 version that I installed from source (a long time
ago) still works, but it obviously can't open up my newer project files.

The crash can be reproduced every time.

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