Bug: Refreshing trigger, which was removed

Hi!

To reproduce:
1) Create trigger on the function;
2) Select this trigger in object browser;
3) Do sql command "DROP TRIGGER ...";
4) Press "Refresh the selected object" button in menu, or click
refresh in the context menu.

This crashes app.

Tested on Mac OS 10.6.7, pgAdmin3 1.14.0 Beta 1 (lastest from git).

Regards,
Aleksey
