            Bug ID: 367900
           Summary: Frequent segmentation fault when splitting tracks in
                    timeline, related to libqtcore5.so Object disconnect
           Product: kdenlive
           Version: 16.08.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: User Interface
          Assignee: j...@kdenlive.org
          Reporter: josh.ruby...@gmail.com

Since upgrading to 16.08.0 on Arch Linux, I suffer frequent segmentation faults
in one specific case.

When splitting a track in the timeline, seemingly 20-30% of the time now it
will crash the application with a Segmentation Fault.  I have attached a
coredump of the problem.

P.S. - lots of *other* annoying bugs were fixed in this release, so thanks very
much for that!  This segfault on track splitting, though, is new and somewhat
debilitating.

Reproducible: Sometimes

Steps to Reproduce:
1. Create a new project, add an mp4 file to the clips area, drag it onto the
timeline, and save it.
2. Split the mp4 file.  I do this after playing it for a bit because I am
editing videos (obviously) and so I watch through them.  I frequently cut out
bits (coughs, etc) and occasionally cut to speed things up (ungroup the clips,
add speed to the video clip, make audio the same length as the sped up video)
3. Make splits of this sort a few times (2-6?)

Actual Results:  
After doing this some number of times (never happened the first cut so far, but
generally happens by the time I've cut 5 or 6 times in one session), the UI
will hang up for a bit and then the window disappears.  This is because of a
segmentation fault.

Expected Results:  
Clip is split and application does not segfault :)

I'm running the nvidia proprietary driver but I doubt that's remotely related
based on the attached coredump.
