crash on startup when password is wrong

When starting mpDris2 0.7 on Ubuntu Linux 14.04 with 0.18.7-1 I get the following crash:

$ mpDris2 --debug

This also happens with latest git master.

MPD_HOST had a password, while my mpd did not have a password set. Thus the password was incorrect, and mpdris2 crashed.
