I searched for this problem but can't implement the suggestions I found. I had DC 1.3.6-0 running for SMS use only. I just got SIP configured successfully to be able to use DC for voice but had to change my GV password as part of the process. Now DC tries to login with old PW and hangs as a result.

I found a post that indicated there is a settings dialog for this but the drop down menu won't let me go to "account". Message says "must be online for settings". Um, if I was online I wouldn't need a settings dialog

Reinstall didn't help. Ideas welcome. Also, If I end up needing to edit a config file directly to fix this, can I get file manager to show me the OS file system rather than the basic view? I'm don't speak enough linux to dig it out via command line.
