6.5.4 zero length field name in format

[Tomasz Żok]

Hi Luis,

I searched for this in my installation (6.5.3.1) and I can see the following
entries:

folder/Base.py:     self.ui.info("[DRYRUN] Copy {} messages from {}[{}] to {}".format(
ui/UIBase.py:       self.info("{}Creating folder {}[{}]".format(
ui/UIBase.py:       self.info("{}Deleting {} messages ({}) in {}".format(
ui/UIBase.py:       self.info("[DRYRUN] {}".format(msg))


I assume similar lines are present in 6.5.4... And this syntax is not supported
by Python 2.6.6.

To fix your error, you should do one of these:
- upgrade to Python 2.7
- modify these files on your own: number the curly braces

If you decide on the second option, note that you should look for any
occurrence of {}, but inside of string (i.e. embedded in quotes "..." or
apostrophes '...'), like the ones listed aboce. A simple grep will give you
also lines like this:

    retval = {}

But these are fine and should not be changes. Here the braces {} are not inside
of string. 

Cheers,
Tomek
