[Eric] Can not run Python scripts and empty Shell - Eric3

[Detlev Offenbach]

Hi,

please open the preferences dialog, Debugger - Python page and check the a 
custom Python interpreter is selected. If this is the case and a non existing 
path is given, startup of the debugger will occur. Please select Standard and 
try again.

The observed traceback is a follow on problem that is caused by the missing 
feedback of the Python debugger. That can be changed by changing line 104 of 
Shell.py to read

self.history = QStringList()

Regards,
Detlev
