So then I tried:

But when I select multiple rows and try to remove them it gives this error:

That likely happens because by removing rows you made one of the later
paths refer to non-existant rows so that $model->get_iter($path) returns
undef. One quick hack that might make this work is to iterate over the
@paths in reverse order. But to be safe you should follow the doc's
advice[1] of converting the paths to Gtk2::TreeRowReferences (which
listen to changes in the model and adapt accordingly).
