So then I tried:

But when I select multiple rows and try to remove them it gives this error:
*** unhandled exception in callback:
***   variable not allowed to be undef where GtkTreeIter is wanted at line 654.

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).
