Bug ID: 381401
Summary: crash when restarting kdenlive after switching from
RtAudio to SDL audio
Product: kdenlive
Version: 17.04.2
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Installation
Assignee: vpi...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
Application: kdenlive (17.04.2)
(Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.35.0
Operating System: Linux 4.9.30-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I noticed saccadic playback when using RtAudio output linked to terminal
warnings (scrolled off my history, sadly) so I decided to try Pulseaudio output
via the SDL module. KDenlive crashed after restarting.
About the backtrace: m_consumer->stop() is Mlt::Consumer:stop() which calls the
C function `mlt_consumer_stop( get_consumer())`, where `get_consumer() !=
m_consumer` but `m_consumer->instance` (and that member variable is indeed
NULL).
-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
