Comment 4 for bug 871869

It looks like the issue is something releated to webkit:

Investigating (2) libwebkitgtk-1.0-common [ i386 ] < none -> 1.3.13-0ubuntu2 > ( libs )
Broken libwebkitgtk-1.0-common:i386 Kollidiert mit on libwebkit-1.0-common [ i386 ] < 1.2.7-0ubuntu0.10.10.1 > ( libs )
  Considering libwebkit-1.0-common:i386 9 as a solution to libwebkitgtk-1.0-common:i386 3
  Holding Back libwebkitgtk-1.0-common:i386 rather than change

Could you please try removing libwebkit-1.0-common and see if the upgrade works then? This will also remove some package that the upgrade should put back in. But to be sure, please write down the list of packages and if the upgrader does not put them back install them manually (sorry for that).
