Bug ID: 370987
Summary: git master:2016-10-17: Application crashes on startup
Product: kdenlive
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: grave
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: evert.vors...@yandex.com
After the most recent update, kdenlive crashes on startup.
This is my testing machine with the nice nVidia GTX 960. I have enabled
pulseaudio output, and I think it is related to this crash.
Reproducible: Always
Here is a backtrace:
