gtk+ 2.10.14 broken with cups 1.3

[Diego Sardina]

This is an issue already fixed in the latest gtk+ stable version, but the  
old stable version (2.10) still has this issue.

Here the patches:
http://svn.gnome.org/viewcvs/gtk%2B?view=revision&revision=18753

there is also a typo fix:
http://svn.gnome.org/viewcvs/gtk%2B?view=revision&revision=18755

I know that gnome 2.20 (with the new gtk+ stable version) will be soon in  
the ports tree, but this fix can be useful for unbreaking the build ;P
