It seems files in the history don’t have a proper path. I guess I should add a null check to the IMP LanguageRegistry class.

This might be related to the fact that Spoofax cannot deal with files that do not belong to a project.
Spoofax should be able to provide an editor based on the file extension, regardless of it being inside or outside of the workspace.
Failure of SSL_EXT_projectpath could indicate a out-of-project file.

Should be fixed in 0.4.4.
