#82 EXIF date issue

[Devon Crouse]

This is likely a duplicate of \"Image EXIF tag time - ID: 1756285\", but that ticket was closed with the comment \"Issue resolved through email.\" What was the actual resolution - issue with the file? Looking at my files in windows, the field looks populated, but metamorphose2 hangs while processing the first one:

Metamorphose 2.0.8.2 (beta)
Running on Python 2.7.3, wxPython 2.8.12.1

<Added insert rule with :date: tag>
status message : \'Previewed 8 items with no errors\'
<Changed to \"Exif tag - picture taken\">
status message : \'Generating 8 new names, please wait ...\'

I\'ve attached a smaller sample image that also causes the issue. Thanks for maintaining the project!

I think I found the problem.

main.encoding in utils.udate is None, and it gets stuck on lines 229 "format.encode(main.encoding)" and 230 "return udate.decode(main.encoding)"

If I just remove the encode/decodes, the method returns and EXIF works fine, but I'm assuming that could break other functionality. I'm not much of a Python person, so I'll let you be the judge of the right fix.
