Description jamie marchant 2016-09-24 20:35:36 UTC

Application: kdenlive (16.04.2)

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.3-100.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
I open the moniotir on a secound and treid playing the video I was working on. It did not play but this is a seprete bug(if it can be reproduced). I can't remember what I did next but I closed a bunch of parts in the layout including the monitor. I palyed the video again and a window that said 'Mplayer' poped up, I treid makeing this fullscreen but it did not work so I dceicid to close it and try again. I hit something like 'view' -> 'monitor' and now the program won't come up at all. I seem to have currupted my layout. As I have some editing to do I will reset my setting by deleting the configuration files.

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault

Comment 1 Wegwerf 2016-09-26 19:35:37 UTC

What graphics card are you using? What OpenGL-related information does Kdenlive report when started in a terminal?

Comment 2 jamie marchant 2016-09-26 19:42:40 UTC

Created attachment 101306 [details]
Output of 'kdenlive' when run from the terminal.

Output of 'kdenlive' when run from the terminal.

Comment 3 jamie marchant 2016-09-26 19:45:31 UTC

I have an ATI Radon 5400 and am using the Kernel driver.(not the 'proprietary' ones.) 

Here is my terminal output in a >> normal run. <<(as I said I had to get the program to work, so I deleted all the Kdenlive stuff in my home folder.) 

I don't see anything OpenGL related in that log.

Comment 4 Wegwerf 2016-09-26 19:51:25 UTC

Do you have OpenGL enabled drivers installed? Kdenlive should report some OpenGL information at startup. Moreover, your crash is trying to open OpenGL.

Comment 5 jamie marchant 2016-09-26 20:03:27 UTC

Yes I have OpenGL enabled drivers and to make sure everything still works I ran the Linux port of Portal 2. The OpenGL stuff must have been removed from the Fedora Cora port of kdenlive? Would you like to see the output of 'glxinfo'?

Comment 6 Wegwerf 2016-09-26 20:07:19 UTC

No, I don't want to see arbitrary output. You should see Kdenlive startup messages similar to this:

OpenGL vendor:  "X.Org"
OpenGL renderer:  "Gallium 0.4 on AMD PITCAIRN (DRM 2.43.0, LLVM 3.8.0)"
OpenGL Threaded:  false
OpenGL ARG_SYNC:  true
OpenGL OpenGLES:  false

If Fedora has incorrectly OpenGL stuff, then please tell your distro packagers to correctly package Kdenlive. Thank you very much for your cooperation.

Comment 7 Jean-Baptiste Mardelle 2016-09-26 20:18:15 UTC

This in fact looks like a duplicate of bug #364278. Kdenlive 16.04.2 crashes on some config. So unfortunately there is no easy fix unless your distro packagers prepare 16.04.3 or 16.08.x versions

Hmm this does look like a duplicate too me.
