Yes. I re-checked. I sent the right file.

STEPS: I open pgadmin. Connect to my local machine. Select the DB. Goto
query tool. close the tool. Pgadmin aborts.

Whenever I close the query tool, I see the core dump. (Same problem -
even when I open the query tool and close or execute quries and close)
This is there both in 1.6.0 and 1.6.1.

I am currently working on this. I will send them ASAP.

This behaviour is not consistent. It is not related to the table. This
problem may occur only certain times (not always) for the same set of steps.
This problem is only with 1.6. 1 and not in 1.6.0.

-
I noticed one more in-consistent problem in the query tool. Sometimes
there is no results displayed after executing the query.

The warning msg that I got was

/usr/local/include/wx-2.7/wx/string.h(363): assert
"stringSrc.GetStringData()->IsValid()" failed in wxStringBase(): did you
forget to call UngetWriteBuf()?
Do you want to stop the program?
You can also choose [Cancel] to suppress further warnings.
