Crash occurs when the user closes the editor while there are blueprint thumbnails visible in the Content Browser. This seems to only occur if the editor was opened with blueprint thumbnails also visible.
I can only reproduce this crash in //UE4/Release-4.13. I wasn't able to reproduce it in //UE4/Main at CL 3065268/
RESULT:
Crash.

There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-33874 in the post.
