We just upgraded to Mocha2020.5 and Nuke12.2v2 and when our artists launch the Mocha OFX plugin it crashes Nuke12.2v2. We are on Centos7
The following is the crash log:
QSocketNotifier: Can only be used with threads started with QThread

I don’t know what uuid_generate is but I think this probably related more to Nuke12.2v2 than Mocha, however I would like to know if you have seen this before and could help us with a fix.
Platform: Using Centos7 Linux, appears to crash in both KDE and Gnome Desktop environments.
Description: We just upgraded to Mocha2020.5 and Nuke12.2v2 and when our artists launch the Mocha OFX plugin it crashes Nuke12.2v2. We are on Centos7
Steps to reproduce: Steps on how to reproduce the problem
Expected result: It launches Mocha and Nuke doesn’t crash
Actual Result: It doesn’t launch Mocha and Nuke crashes
Regression: Nuke didn’t crash on older versions of Nuke and Mocha
Additional data: Crash log

I ran some more tests and it appears to be an issue with Nuke12.2v2 Nuke12.1v3 doesn’t have the issue.
So at this point, I am not sure if it’s Nuke’s bug with OFX support or if it’s something that can be added on your end.
I checked with support, it’s a known issue we will work to address. There is a workaround according to our notes: When running Nuke, use the LD_PRELOAD environment variable to add libuuid. For example:
1LD_PRELOAD=/usr/lib64/libuuid.so.1 ./Nuke12.2
Maybe try that too and see if it works for you. If you need any more information, I’ll let Martin chime in. That’s the limit of what I know right now on this specific issue.
