I've had the same thing occur on my system lately.
It seems to be RED Giant Universe plug ins. Sometimes I can clear the transitions before the program crashes, other times I've just uninstalled universe, re-save the file with the transitions cleared, the re-install universe. Knoll light factory was crashing it the hardest.
Im using windows 7 with intel 4790k, 32 gb of ram, gigabyte GTX 970, Gigabyte z97-hd3p motherboard.
