Kerbal101

Hi, Mat van Kerman! This is a known and confirmed issue, I've definitely encountered it on the bugtracker.

@Jack5.exe Hello again! Thank you! I have added the log link that you posted into OP, I hope that it is okay!
Personally, I can only think of the problem with mod that is stored in the "BlueDog" folder, as it is last to see in the logs right before the crash.
I recommend to move it out of Gamedata and rerun the game. In general, by moving half of the mods out of gamedata until the problem is solved - you can essentially  bissect the cause and then report it into development thread of that specific mod.
Unfortunately, this is all I can help. Perhaps other members may come to assist you, if the above does not work.
Kind regards

You can get some answers yourself in a fun and interesting way.
"Does it take the same dv to leave Kerbin to a given planet as leaving the less massive Minmus, considering that Minmus is orbiting at a speed one perhaps could use to one's advantage? "
Make a lightweight probe, from OCTO, TR-18A stack decoupler (deactivated), four small fuel tanks with legs, one tiny engine below and antenna.
See that it has around 1000dV, you can get this through KER - current and total stage dV are displayable, then just bring one copy to Minmus surface - and leave one copy on Minmus.
Do typical maneuver nodes for both, writing down changes in deltaV before and after each maneuver and you'll get exact answers yourself. =) 
"How does 5620 sound for a polar orbit around Moho?"
The stronger the gravity force, the lesser efficiency (TWR) engines can provide. Thats why changing inclination is best done in distance, I call it "injection correction".
Burn normal/antinormal to change inclination and radial-in/out to change approach distance to surface, usually it takes a handful dV (~100-50) if done in distance.
"How about radiators?"
Depends.. Moho is hot, but not too hot. The critical distance to Kerbol is around 600,000,000 m, the "low orbit" is around 1,000,000,000 m.
These are values which I got with own lightweight probe, it really makes large part of fun it.

@Wollknäuel This is actually caused by still attached fairing (above in your craft) and it has been fixed in 1.2.

This is a bug caused by fairing that is still attached to the craft after deployment and it has been fixed in 1.2.

From 1.2 changelog:
 

Found this.
 
Edit: The above was marked as main issue, this is duplicate which matches your issue.
