crash when ALT+TAB from connection dialog and back

when I press the connect icon and then press connect I have to enter the password for the MySQL server since I dont save the password.

Then I ALT+TAB to my password manager and copy the password and ALT+TAB back to the "Login" dialog

A lot of the times when I ALT+TAB back to the login dialog I crash.

I have a bugreport that I can attach
