renaming project root directory cause IllegalArgumentException

[piotrekkr]

After renaming project root directory in PHPStorm 7.1.3 (right click on root project directory -> refactor -> rename -> rename directory) I get IllegalArgumentException from gitignore plugin.

Error message:

update failed for AnAction with ID=Gitignore.IgnoreGroup: Argument 0 for @NotNull parameter of com/intellij/openapi/vfs/VfsUtilCore.isAncestor must not be null 

Details:
