LMDE mintBackup broke with debian update to pythin-apt 0.8.0

[Mike T]

With the release of python-apt 0.7.100, the debian folks announced "Applications using the old API should be updated to the new API because the old ones will be dropped in a future release. To build a python-apt variant without the deprecated API, build it without the -DCOMPAT_0_7 compiler flag." With the 0.8.0 release, which appears to have hit wheezy fairly recently, the deprecated API was dropped. (http://apt.alioth.debian.org/python-apt-doc/whatsnew/0.8.0.html)

So, I'm sure mintBackup wasn't the only thing hit by this, but mintbackup is broken. The traceback looks like this:
$ mintbackup
Traceback (most recent call last):
  File "/usr/lib/linuxmint/mintBackup/mintBackup.py", line 87, in <module>
    class MessageDialog(apt.FetchProgress):
AttributeError: 'module' object has no attribute 'FetchProgress'

I've found the equivalent class in the new api. By importing apt.progress.gtk2 and then changing line 87 as follows:
-class MessageDialog(apt.FetchProgress):
+class MessageDialog(apt.progress.gtk2.GOpProgress):

things appear to run properly again.

I'm testing now and working on getting myself setup to submit the patch (as I'd like to contribute where I can anyhow, this seems like a great place to start).

I've examined the other python-apt calls in this script and from what I can tell, they seem to be supported, but I'll continue testing and update if i find anything else.

I'm running LMDE Xfce 64bit, fwiw.

M.Thompson: your patch worked for me too. I built mintbackup on a PowerPC computer running Wheezy.

Thanks for the patch and the detailed analysis.
