Crash "The memory could not be read" on Windows XP

Hi,

Pgadmin3 (version 1.12-beta2) crashes with an "The memory could not be
read" error on my Windows XP Pro.

I can reproduce it this way :

1. connect to an Postgresql 8.4 or 9.0 server
2. go to the schema in the left panel of pgAdmin
3. create a table with no column
4. right-click on the table, add a column
5. fill the fields :      name : col1,      datatype : character varying (or bigint...)
6. click on the "OK" button.



Versions of pgAdmin : 1.12-beta1 and 1.12-beta2 (Jun 3 2010, rev:
8398:8401)
(I have tested both)
I do not have the problem on an older 1.10 version of pgAdmin.
System : Windows XP Pro, in French (so pgAdmin is in French too)
Database : Postgresql 8.4 or 9.0



Since I do not know if the problem is caused by my system, or pgAdmin
itself, I tried to lauch it via the command line. But there is no other
error message.
I do not see anything in the Event Observer of Windows.
