exec error in DistUpgradeControler

[Rachael]

Binary package hint: update-manager-core

Running an x86_64 feisty install (originally upgraded from edgy) on a laptop. While installing updates this morning, the upgrade manager warned me that there it needed to do a distribution upgrade because some updates couldn't be installed. As there was a linux kernel (I think) update in there, this wasn't terribly shocking. When I clicked the Distribution Upgrade, I got this error:

   controler = DistUpgradeControler(view, datadir=data_dir)

  File "/usr/lib/python2.5/site-packages/DistUpgrade/DistUpgradeControler.py", line 127, in __init__
    if self.options.mode == "server":

AttributeError: 'NoneType' object has no attribute 'mode'

I then got as many things to install normally as possible (possibly stupid) and tried again with the same error. I then changed the .py file to change the "if self.options.mode == "server"" line to read:

        if not self.options and self.options != None and self.options.mode == "server":

and the distribution upgrade could be re-run without errors. (I do not know python hardly at all, so my changes here are probably not "right").

Thanks for your bugreport.

This is fixed in my local tree and will be part of the next upload.
