Crash when specific call is made

[linuxgurugamer]

I'm working on updating FMRS to 1.2.2, and am running into a stone wall.

In the code, there is a call to load a save and go to a specific vessel, the call is:

FlightDriver.StartAndFocusVessel(loadgame, load_vessel);

On a minimal game, where there are no other mods installed (MM & the KSPDev logging mod being also isntalled), I am getting a consistent crash whenever a call is made to the function.  since it's a crash, I can't see where it's crashing, am hoping someone can give me a clue.

The only thing I have been able to come up with is that it wasn't crashing when I had a lot of mods installed, so I'm wondering if there is some sort of timing issue going on.

Here are the crash logs from the latest crash.

Edit:  installing a single mod, Janitor's Closet, made it much more stable.  But JC doesn't do anything other than working with the toolbar
