mysql plugin will not work with certain string in password

[brandonfouts]

If you use a mysql password that contains #4b it will not log into mysql using the plugin. You can actually just set your password to #4b and the plugin will not login.

To mimic this issue create a new user in mysql:
CREATE USER 'brandon'@'%' IDENTIFIED BY '#4b';
GRANT ALL ON . TO 'brandon'@'%';
FLUSH PRIVILEGES;

Then create your 1password entry and set the password to #4b and try to use the plugin.
