Comment 3 for bug 764184

Then can you tell me what I am doing wrong? I tried "Save Tags" months ago before I posted in the forum and filed the bug report, and I tried it again now but it still is not working for me. I've tried using "Save Tags" pointed to the source folder and to a different folder but I get the same thing - an error message and the original image jpg file changed to a 0 kb jpg file. Using "Save" works just fine, but it is not lossless. Attached are screenshots of my action and the error message. Following is the log:

Error 0:Can not apply action Save Tags on image 'P8071777.JPG' in folder:
/home/edward/Pictures/Trial

local variable 'warnings' referenced before assignment

Action:{'fields': {'File Name': u'<filename>',
            'In': u'/home/edward/Pictures/Trial',
            '__enabled__': 'yes'},
 'label': 'Save Tags'}

Traceback (most recent call last):
  File "/usr/share/phatch/phatch/core/api.py", line 614, in apply_action_to_photo
    photo = action.apply(photo, read_only_settings, cache)
  File "/usr/share/phatch/phatch/actions/save_metadata.py", line 47, in apply
    info.save(filename)
  File "/usr/share/phatch/phatch/core/pil.py", line 440, in save
    return warnings
UnboundLocalError: local variable 'warnings' referenced before assignment

Thanks

Ed
