Post your questions to the pgadmin-hackers mailing list - that's where
we discuss this sort of thing.

What *exactly* are the steps your using to recreate the problem?
The only thing that stands out in the back traces is in the second one:
0x08211e62 in frmMaintenance (this=0x91b1800, form=0x8cb8108, obj=0x0)
The line it's crashing on (54) is trying to use the variable 'object'
which is set to the value of 'obj' in in
ExecutionDialog::ExecutionDialog. As you can see, that is null which
is why it crashes. You need to traverse back up the stack and see
where that value is coming from. Understanding how it gets set to null
when it clearly should be a pointer to a valid object also requires
understanding exactly what steps you follow to cause the problem in
the first place.
