mscorlib.resources.dll

TBH, I'd never heard of it before and it's not present on my Windows 7 machine or .NET framework set up, though I don't have the language pack installed.

However, judging by this MSDN thread, I think you may be right that it is something to do with the language pack - perhaps it contains stuff like error messages in non-English languages:
