Comment 4 for bug 1194129

This last patch fixes the error "variable length array of non-POD element type 'Glib::ustring' " in src/ui/dialog/inkscape-preferences.cpp:1243:29. However, I had to backport all of revision 10062, because I don't know how to edit the C code to do a minimal change to just that file. Therefore, I just searched for the earliest code that got around the issue. This unfortunately causes string changes.
