Running latest trunk build on 32-bit Linux, pgAdmin crashes whenever I
click on a schema that contains one or more domains.
GDB backtrace: http://pastebin.com/mSGd978J
To reproduce:
1. Create a new database
2. Create a new schema in the database
3. Create a new domain in the schema.
pgAdmin crashes at this point. If you restart it crashes as soon as you
click on the schema that contains the domain in the treeview. Clicking
on a schema with no domains is fine.
