Image conversion error with accented characters - python files have no encoding

[Uwe Stöhr]

When I open a LyX-file that is in a path with spaces. I get the 
following error message when included images should be converted to be 
displayed:

---
File "C:/Documents and Settings/usti/Local 
Settings/Temp/lyx_tmpdir2816a00220/lyxconvert0.py", line 11
SyntaxError: Non-ASCII character '\xfc' in file C:/Documents and 
Settings/usti/Local Settings/Temp/lyx_tmpdir2816a00220/lyxconvert0.py on 
line 11, but no encoding declared; see 
http://www.python.org/peps/pep-0263.html for details
---
The problem is that the temporarily generated python files don't have a 
defined encoding. The encoding should be the one of the current OS 
setting. Bo, is this possible to have?

To test, open a small Lyx-file that contains an image from a path like , 
e.g. "C:\touché".
