Why does this Program run from Aptana IDE and not in python command?
The following code results in a
htmlbody,emailaddress = ConnEmailParser()
TypeError: 'NoneType' object is not iterable
Error but works fine in IDE. Emails are being sent and PDF files generated. But from command line just ConnEmailParser() is working.
What can I do, that the program runs smoothly?
Here the code snipped:

In def ConnEmailParser(), check if data is None before calling data[0].split().
If it is None, check if imap4 is correctly initiated and if login worked. If that is the case, post a reduced part of your code pinpointing on where it actually goes wrong.
As @Jim Garrison pointed out, a traceback would help us (and you) a lot. This is how:
import traceback
try:
some_code...
except TypeError:
traceback.print_exc()
edit (based on your comment)
When you encode a unicode string, you are replacing characters that are not part of ASCII with codes as '\xfc'. Apparently, saver.write() tries to encode your already encoded text, after first interpreting it as unicode (you got u'\xfc'). So don't encode yourself. If it still goes wrong, see how you can change the encoding (e.g. 'utf-8', 'cp1252'). Get the current encoding of your OS with
import locale
encoding=locale.getlocale()[1]
