Yes this happens because of the gtksourceview3 (3.8.0-1).
It has a new so-name.

We have to loosen the dependencies of the gtksourceview (like it is done in the Gnome3 Staging PPA) or better, have a new gedit built against new gtksourceview3.

This issue is fixed now with a new gedit build (3.8.2-0ubuntu1) in Saucy proposed repos.

If you aren't willing to put up with breakage, I'd suggest you disable the proposed archives, as the developers have warned us all that proposed will break your distribution more often then not. the proposed repositories don't work the same way during the development cycle as they do for a released version. They are used as a holding area for new packages that are waiting for dependencies to be built before being moved into the regular repositories.

This did not happen to me but, cariboo907 while asking what appears to be a dumb question which are "the proposed archives"?

I see a key Ubuntu Archive, but that is all I see mentioning archive in my software sources.

@Cavsfan, see the screenshot of Software & Updates, on how to enable/disable the proposed repositories.

[deadflowr]

@cavsfan, you can also comment the proposed-updates lines in the sources.list, if you want.

But +1 to disabling proposed in development, it's not used like normal proposed in the stable releases.
They don't do solid testing like stable proposed, it's more like a staging area now.

Glad I asked because I had Pre-released updates checked! Not sure If I checked it myself or what.

I got confused when you said

But, then again I am easily confused.

Thanks deadflowr but, as you said unchecking the box was the easiest thing possible.

Think I am good to go now. Good thing I spotted this.
Thanks!

The proposed repositories make the difference between the Edge and the Bleeding Edge in running Ubuntu development. The blood on the bleeding Edge has to come from someone.

There is still a good amount of blood on the edge, without proposed.
