GQB bug - Segfault in 'Join' tab - Mailing list pgadmin-hackers

Hi all,

I'm testing GBQ a lot here and i'm get an error when I follow this steps:

1) Open pgadmin3
2) Select a database that contais a schema with ~ 450 objects
3) Open the Query window
4) Switch to the GQB Tab
5) Wait for ~8s until all my objects appears
6) Drag and drop 3 tables (one parent and yours 2 childs)
7) Using the mouse, I make the relationships between them
8) Right click and anybody of 2 childs and choose "Delete table"
9) Drag and drop back it again and repeat 7-8
10) Bring it again and click in "Join" tab and bum! Segfaul...

The gdb's debug output  is attached... I hope it helps...
