File upload gives UnicodeDecodeError

[ambre]

Hi,

I'm using webpy-0.31 and when I try to upload a JPG file, I get this
error (same file upload worked fine with webpy-0.2x).

Traceback (most recent call last):

File "encodings/utf_8.py", line 16, in decode
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0:
unexpected code byte

The error is triggered by calling web.input().

file uploads have to be declared like so:

web.input(file={})

Yes I know, and I did it this way.
Here my further investigations:

This works:
f = web.input(datei={})
self.datei = f['datei'].value

Put this gives me the error bellow (here I also use web.input().name:
f = web.input(datei={})
self.datei = f['datei'].value
self.name = web.input().name

My form has not just the file fieled but also at least a name field.

This should be:

self.name = f.name

This works!
Many thank's to you and all the developers of webpy!
