pgAdmin 1.6 beta password issues

I had sent a version of this bug report to Dave Page directly a few days
ago, but let me clarify and do it through the forum. It seems that
pgAdmin 1.6 beta on windows suffers from some old password issues -- one
that is consistent, the other one I cannot reproduce reliably:

(a) the intermittent/not reproducible one -- the pgpass file gets
corrupted eventually and I start seeing lines like this:

bcde::::
alhost:5446:*:mno:vwxyz

where "abcde" is a user name and "vwxyz" is a password, so the first of
the above lines has a chopped off user name in the first position (where
the server name should be) and a bunch of blanks and the second line
looks almost OK except that the server name is chopped off. This happens
with ONLY pgAdmin (no psql) connecting from this Windows machine.

(b) connecting the last server defined in the pgAdmin tree always starts
off with an error. To reproduce:
1. start with a cleaned-up pgpass file (remove all weirdnesses as
described in (a)
2. make sure the last server in your tree has a saved password (save a
password through the server definition in pgAdmin and verify that the
pgpass file looks correct).
3. close and reopen pgAdmin
4. double click on the last node in the server tree (in order to open
a connection to that server)
5. get error pop-up "An error has occurred: Error connecting to the
server: fe_sendauth: no password supplied"
6. close the error window
7. double click on same node again
8. now you get the connect to server dialog with the "store password"
checkbox on (so it knows that the setting is to have it saved) but no
password in the textbox
9. type the password
10. now you can connect
As you are doing all this monitor the pgpass file and note that it is
not changing at all: the line for that server was there at step 3 and is
there after step 10 (the file timestamp does change [at step 10], but
none of its contents are changed).
