Hi,
I have just built and installed wxPython 2.8.8.1 (based on wxGTK, which I have also just built), and when I try my test application, it fails with the following error:
File "wxtestapp.py", line 422, in ?
app = Application(0)
File "wx/_core.py", line 7913, in __init__
self._BootstrapApp()
File "wx/_core.py", line 7487, in _BootstrapApp
return _core_.PyApp__BootstrapApp(*args, **kwargs)
File "wx/_core.py", line 7922, in OnPreInit
wx.StockGDI._initStockObjects()
File "wx/_gdi.py", line 6181, in _initStockObjects
wx.TheFontList.this = _wxPyInitTheFontList().this
AttributeError: 'NoneType' object has no attribute 'this'
I am assuming that I have built wxPython (and/or wxGTK?) incorrectly. But I don't have the slightest idea as to how to go about fixing this. Any pointers/advice would be very helpful.

_wxPyInitTheFontList is C++ code that looks like this:
wxTheFontList is a global pointer that should have been initialized during the C++ part of the BootstrapApp before it called OnPreInit, but apparently in your case it is not doing so and is returning NULL instead, which the wxPython wrapper is turning into None.
So the thing to do would be to use the debugger and put a breakpoint somewhere in the startup/initialization code and trace it through and find out why wxInitializeStockLists is either not getting called or is being called but the allocation of the stock list objects is failing.
