Crashed on closing the kdenlive.
Comment 1 Christoph Feck 2017-01-01 15:42:26 UTC
Are you using nvidia binary drivers?

Yes I am.

Happens to me to. Fedora 26, Kdenlive 17.04.2 crash on exit.
kcrash tells that the backtrace is probably not useful, well I attach it anyway.
I'm also using nvidia binary driver.

Comment 5 Leszek Lesner 2017-08-16 14:58:35 UTC
The crash is actually happening in the melt framework and taking kdenlive down aswell. 
This commit (6 months old already) in melt fixes the issue:
https://github.com/mltframework/mlt/commit/a3188e301b5a9a1f25dbb98a510e366363348e64

We added the fix to our mlt packages in Neptune since then and don't suffer from kdenlive crashing any longer. 
As no new melt version (e.g. 6.4.2) was released I suggest all distros should patch melt in the meantime until it is fixed. (or someone from kdenlive can poke the melt guys to do a new bugfix release so distros can pick up the fix amongst others)

Status should be set to confirmed btw. or something indicating that it is an upstream issue within melt.
Comment 6 Attila 2017-08-31 19:18:16 UTC
I can confirm the crash on Fedora 26 x86_64.
I am using the nouveau driver for NVIDIA GeForce GT 630.
Comment 7 Christoph Feck 2017-09-05 20:10:42 UTC
Leszek, what you see is probably bug 378469.

backtrace from exit crash

Also happens on kdenlive 17.12.3 on openSUSE using the version from the Packman repositories.
Comment 9 John Carrick Smith 2018-04-19 13:29:21 UTC
Upgrading libmlt... to 6.6.0-13.1 from Packman fixed this.
Comment 10 Andrius Štikonas 2018-04-23 20:47:09 UTC
Fixed by mlt 6.6.0 here too.
