Crash on selection / Import transforms

[mrharris]

When I click on a proxy mesh in the viewport maya will crash. This happens with all tried viewport modes,

• viewport2 w/ legacy opengl
• viewport2 w/ compatibility
• legacy viewport
• with and without MAYA_VP2_USE_VP1_SELECTION=1

It also give the same stack trace if I select the ProxyShape and use "Import Transform as Transforms"
