That is correct. Eric3 comes with three debugger (interpreter) types. One that 
requires Qt (3), one without this requirement and a multithreaded variant of 
the non Qt variant. The Qt variant is the default one, but that can be 
changed globally (Configuration dialog) or on a per project basis (Project -> 
Debugger -> Debugger Properties). Eric4 will just contain the non Qt 
interpreter variants unless I receive reports, that this will cause problems.
