After launching to the pad and then reverting, a nullref flood begins and continues until the part is destroyed.
This folder contains ksp.log, and a folder called CustomDecals with a single atlas-style decal part, included for completeness, and because this log references this part. However, I've had this same problem with regular flag CDL parts, as well.
The steps in the log are: start the game, enter VAB, open craft, launch, revert, exit game.
Very odd, never seen this one before. I wonder if it could be an incompatibility with another mod (KSPCF maybe?). If you can, please try to reproduce with only CD
