#376 Easily corrected error cause failure to open debugger

Hi,

when entering the debugger through a break-point or post-mortem, I often get the following traceback:

File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\debugger\__init__.py", line 110, in post_mortem
p.done_run()
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\debugger\debugger.py", line 542, in done_run
self.RespondDebuggerState(DBGSTATE_NOT_DEBUGGING)
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\debugger\debugger.py", line 769, in RespondDebuggerState
cb.RespondDebuggerState(state)
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\debugger\debugger.py", line 202, in RespondDebuggerState
self.list.Refresh()
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\tools\hierlist.py", line 215, in Refresh
self.AddItem(hparent, newItem)
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\tools\hierlist.py", line 140, in AddItem
text = self.GetText(item)
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\tools\hierlist.py", line 266, in GetText
return self.DelegateCall( item.GetText )
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\tools\hierlist.py", line 255, in DelegateCall
return fn()
File "C:\Quantax\trunk\Zope\Python\Lib\site-packages\pythonwin\pywin\debugger\debugger.py", line 58, in GetText
name = self.myobject.f_locals['__name__'] + " module"
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

This can be corrected easily by putting an str() around
self.myobject.f_locals['__name__'] in debugger.HierFrameItem[58] or a get with check against None instead of the has_key() in the line above.

I did not investigate why the f_locals exists and is None, just cured the symptoms.

Best regards, Martin

I've run into this myself on rare occasions. This seems fairly
safe and doesn't break anything, so I've committed it.
