Define new type: clicking "Define view+list" sometimes reports type already exists

[gklyne]

There is a possible "Define view+list" bug in the software that needs investigating: when clicking "Define view+list" while defining a new type in the type definition view, a message saying the new type already exists may be displayed.

If this happens, , click Cancel then select the new type in the "List types" display and click Edit. Then click the Define view+list button.

(I'm not sure if this Is now fixed.)
