Thanks.  Here are a bit more details as well as an overview of the
problem at the end.

1) When all goes good:

[...]

(mixbus32c-4.3.19:5474): Gtk-WARNING **: Unable to locate theme engine
in module_path: "adwaita",

Color shuttle bg not found

ardour: [INFO]: Loading color file

/home/mevla/.config/mixbus4/templates:/opt/Mixbus32C-4.3.19/share/templates

run dialog


2) When it will not launch, the last two lines ('Found' and 'run
dialog') are replaced by:

ARDOUR_DLL_PATH not set in environment - exiting


I haven't browsed the code, although it looks like
export_search_path() is not a function that would return something
important, if anything at all.  It's assumed it works.

So it's later on when that variable is actually needed and checked
upon that the problem is reported.

This said, restarting jackd solves this problem.

The idea behind asking these things is to perhaps just get a slight
overview of how these things works regarding a problem that breaks the
workflow: linVST crashinbg sometimes, and in crashing puts jacks in a
bad state such that jackd will report:

JackPosixSemaphore::TimedWait err = Connection timed out

JackFreewheelDriver::ProcessSync: SuspendRefNum error

JackAudioDriver::ProcessGraphSync: ProcessWriteSlaves error, engine
may now behave abnormally!!
