Commented Unassigned: Error: Failed to configure settings for runsettings plugin ... [121]

Hello,

thanks for this great tool!

I am facting the following error when opening the Test Explorer:
```
------ Discover test started ------
Failed to configure settings for runsettings plugin 'VSTest Run Configuration' as it threw following exception:
'An error occurred while parsing EntityName. Line 1, position 33.'
Please contact the plugin author.
========== Discover test finished: 0 found (0:00:00,0605121) ==========
```

The tests are running but I wounder what causes this problem?

Comments: my guess is that the path length was the issue. Saying this without verification. - Visual Studio 2012, Update 2, englisch on a Window 7 64. - A co-worker used the same settings without a Problem.
