Ensure occurs when trying to submit to source control after enabling a plugin in the editor. I wasn't able to reproduce this if the uproject wasn't checked out.
RESULT:
Ensure.
Ensure condition failed: false [File:D:\Framework\Engine\Source\Runtime\CoreUObject\Private\Misc\PackageName.cpp] [Line: 624] Illegal call to DoesPackageExist: '../../../QAGame/QAGame.uproject' is not a standard unreal filename or a long path name.
