Crash to desktop every time I rendezvous while entering SOI

[Overheal]

This happened with an unmodded install as well. Happens extremely frequently: 

1. Have a tracked object (relay, station, etc. etc.) in stable orbit around an SOI

2. Burn for that SOI from another SOI (eg. Shuttle from Kerbin->Minmus enroute to Mint Chocolate Shipyard, Minmus)

3. As part of step 2 or a correction burn, set up your transfer flight plan so it intersects with your target

4. Set up your rendezvous/intersect burn (which also slows you down from a transfer flight path to a stable orbit around the new SOI, eg. Minmus

5. Now crashes begin happening, usually when you begin your rendezvous burn, sometimes right after you plan your rendezvous burn, sometimes when you warp to the maneuver. Crashes straight to desktop without error. Not related to proximity to target (eg. not tied to the pop-in from 2.2 km away) 

Workarounds tried: -force-OpenGL (spelling?), -force-d3d11, lowering conics limit - the only thing that seems to work (however frustrating) is unselecting the rendezvous target until a stable orbit is achieved in the SOI, ie.

i. start your rendezvous maneuver,

ii. When your maneuver achieves your earliest stable orbit, you can re-set the target

iii. Burn retrograde to target for final stop

The other other workaround is, of course, to circularize at the destination SOI before attempted to set target or rendezvous but this adds extra burns, time, and delta-V costs.  The problem seems to be that the back-end is getting some unhandled exception trying to calculate your intersect 1 & 2 with target as well as your new orbit data as you are both transitioning to the new SOI orbit and meeting your target. I'm not a programmer per se but it seems like it gets very upset performing that math especially during the burn as the values change violently. Any better workarounds or fixes for this bug? 

EDIT: Been playing around with such a burn/crash, and it looks like I can consistently trigger the crash by looking at the Intercept Info Tab in the Maneuver Data Panel (bottom left of screen), the crash does not happen if looking at the Orbital or Advanced Orbital tabs. Something about having the intersect tab open while you're burning and not in a stable orbit yet/still on track to leave SOI. If I don't look at this tab, the burn happens successfully but can we not fix this bug?

I know it's been a while but I just want to say thanks for posting this. It's still very much a problem in the latest version and it's been driving me nuts while doing resupply runs for my Mun station.

Staying away from the maneuver node panel seems like a solid fix for now. I'm wondering now if it's possible to bypass the game's broken rendezvous math and replace it with that of KER or some other mod. There were mods that fulfilled that same functionality long before it was added to base game, after all. And they didn't have this issue.
