When I open the test project and I click on Test Lists tab, I receive several error messages:

Unable to load test list 'C:\auto02\UI_Automation02\TestLists\Major Sateon Test (AAAAA).aiilist'! Please try loading the project again.

In the log file there is the following exception:

<>c__DisplayClassf.<Refresh>b__5() : EXCEPTION! (see below)
     Situation: Cannot load test list 'C:\auto02\UI_Automation02\TestLists\Major Sateon Test (AAAAA).aiilist'!
     Outer Exception Type: Microsoft.TeamFoundation.VersionControl.Client.MappingConflictException
     Message: The path C:\auto02\UI_Automation02 is already mapped in workspace dswalsh_DSWTest_WebUITestStudio.

This issue happens for random test lists every time with no obvious pattern.

The test project and the log file are attached in the internal description.
