If you start vvvv with a --package-repositories pointing to folder where a lib contains an empty document, vvvv fails to start. The splash screen shows up for a few seconds and then disappears, leaving a ghost vvvv.exe process that has to be taskkilled.
Using --log shows the following exception :
Exception

System.Xml.XmlException: Root element is missing.
Usecase is the following : I was about to create a new package, so I created a VL.Foo folder, and from the explorer right-klick menu created an empty VL document caled VL.Foo.vl so that I could start working directly on it.
Started vvvv with GammaLauncher and pointed the package source folder to the folder containing VL.Foo and got this behavior.
Deleting the empty VL document solved the issue.
Thanks for considering!
