SUMMARY
The VST scan that Kdenlive performs on startup fails crashes after scanning the
Windows VST "VBE-1 Vacuum Tube Bass Enhancer.dll" that comes with Acoustica
Mixcraft 9 Pro Studio. As this is a paid application, I cannot share the
offending VST. The VST is run through yabridge, which uses Wine to support
Windows VST plugins.
It appears that Wine crashes, which takes Kdenlive down with it. As a result of
the crash, I can no longer start Kdenlive, and I cannot find any way to disable
the VST scan. I will try blocklisting this plugin via yabridge and report back.
STEPS TO REPRODUCE
1. Purchase and install Acoustica Mixcraft 8/9/10 Pro Studio.
2. Install yabridge (https://github.com/robbert-vdh/yabridge) and configure it
to find Mixcraft's VST plugins.
3. Start Kdenlive.
OBSERVED RESULT
Kdenlive crashes during the VST scan.
EXPECTED RESULT
Kdenlive should be able to handle the VST plugin scan failure somehow so the
application can be started. At least an option to disable the VST plugin
support would be a helpful workaround for now.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon 6.2
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1
ADDITIONAL INFORMATION
I have attached terminal and debugger output during the VST plugin scan that
causes the crash. I tried to paste it in this comment as suggested in the
Kdenlive bug reporting documentation, but it exceeded the allowable bug report
length.
