Backtrace from Plasma Crash ( DrKonqi )
Comment 4 Rick Timmis 2015-11-12 11:41:33 UTC 
I am trying to something similar, trying to login to Google account. Authentication fails with incorrect password, but I am supplying the correct password ( See ScreenShot ).

Going back to Accounts configuration, I Select the Google account, and click Configure button. Both Telepathy settings and Plasma crash ( Plasma Backtrace attached also ) along with screen shot so you can see exactly what I am doing.
