Yeah, unfortunately there's no bug report about it. Someone reported it 
to me and bisected the regression awhile ago when I sent it the first 
time, but they use an old VST plugin called "Audio Damage EOS", which is 
not available anymore (it's been superseded for a long time, apparently).

So I've been unable to test exactly what's going on, but going by the 
commit they bisected and adding this check, they said it fixed the 
problem—unfortunately I haven't been able to get in contact with them since.

I'll try and see if I can reproduce this in tests in some way or what 
exactly causes it.

Thanks,
Gabriel
