Fix: popup menus were not freeing operators.
Made a new Popup menu call for this case:

uiPupmenuOperator(C, maxrow, op, propname, menustr);

It will set enum "propname" to the menu item and call operator,
register it optionally and free it. Use it in "invoke" calls.

Next: automatic menu generating for enum properties!
