Mixbus crashes when quitting

[fuxoft]

When I quit Mixbus 4, it hangs for about a minute (with single cPU core running at 100%) and then dumps the core. I am using JACK which I start separately (not from Mixbus). During all this JACK keeps running. The last lines in the terminal output are:

Code:

What happens if you remove the Glitch2 plugin from your session?

What happens if you remove the Glitch2 plugin from your session?

I observed the following: When I load the session, do some simple edit, save it and then quit, Mixbus DOES NOT CRASH, regardless of Glitch2 being present or not.

However, previously I experienced this bug several times after longer work sessions, some of which did not include Glitch2. I will try to reproduce the bug reliably...
