Xbuntu / AMD
Short description of error
When in edit mode, alt+right-click should give you an edge loop selection but it doesn't work for vertex or face, only edge.
Exact steps for others to reproduce the error
Select all vertices
Subdivide the cube to make it more complex
Hold down alt and right-click an edge between two vertices
...it should make an edge loop selection... (this also doesn't work for face)
