I had the problem where my kerbals had been on EVA, sitting in Command Seats on a rover. After updating to 0.23.5 (and then to .464), they would stand frozen, on the rover, after I selected "Leave Seat". After finding this thread, I changed "type = Base" to "type = EVA" for both of them, reloaded the modified quicksave, and they were able to move.

For Steam users, take a look in C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\KSP.txt The first line should have the full version in it, including the build number.
