Blank window when internet accounts asks for password change
I'm on OSX Yosemite and I've got a gmail account that I've just changed the password to. I keep getting a pop up from system prefs to change my password. Clicking on the pop up takes me to internet accounts, but another window pops up and its blank. I managed to change my password for the account on the mail app, but now I'm trying to send an email and the pop up is back and I have no idea how else to change my password.
Here's a screen shot of the screen.
