It's because of how python reads strings. The character combinations "\t" and "\a" are converted to some special character. This paths are messed up because of this when those combinations are in the path.
So instead of this correct path:
C:\Documents and Settings\alee\Local Settings\Temp\capA4.tmp\PythonLibs.zip
python reads it as this incorrect path (the "\a" is replaced by a non visible character):
C:\Documents and Settingslee\Local Settings\Temp\capA4.tmp\PythonLibs.zip
