For this use case, I'd recommend you using directly a HildonPickerButton
instead of creating a button, a dialog, and all the logic by hand. Check
the docs for HildonPickerbutton.

I am not familiar with the python bindings, so I have not much to say
about these errors other than it seems that the registration of some of
the types fail, which is strange..

HildonTouchSelector uses HildonTouchSelectorColumn for each of its
columns. Since you want one single column, you need to create one and
use the GtkCellLayout interface in the same way you would do for
GtkTreeViewColumn.

Maybe the python bindings are not fully working? Did you try with C
instead?
