add handle not working all the time

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create a cube
2. select the create handle tool, keep the default values
3. select 2 faces with an edge in common
4. the handle is not created every time

What is the expected output? What do you see instead?
should create the handle, doesnt create it, no error message or anything, the 
two faces stay selected. 
pressing esc and reselecting them few times eventually creates the handle.
