selenium - problem with big file upload

Problem

Selenium 2.25.0, python 2.7, ubuntu 12.04, Firebox 4.0 (yes, old version but we need it) hangs when uploading a file larger then (about) 600KB.

Solution

For now I fixed this by commenting out local file upload (three first lines):

   def send_keys(self, *value):
        """Simulates typing into the element."""
        #local_file = LocalFileDetector.is_local_file(*value)
        #if local_file is not None:
            #value = self._upload(local_file)

        typing = []
        for val in value:
            if isinstance(val, Keys):
                typing.append(val)
            elif isinstance(val, int):
                val = str(val)
                for i in range(len(val)):
                    typing.append(val[i])
            else:
                for i in range(len(val)):
                    typing.append(val[i])
        self._execute(Command.SEND_KEYS_TO_ELEMENT, {'value': typing})

Usually I do not change external libraries code, but in this case it is easiest way and it should not be necessary (I hope) after next selenium library update.
