Cannot switch profile using the profile dropdown

[waldner]

Describe the bug

Choosing a profile from the "select profile" dropdown menu does nothing. The currently displayed profile does not change.
To force a profile change, I have to open configuration -> profiles -> manually enter the desired profile path in the "current path" textbox -> ok.

If I run the app from the command line, this is shown upon startup:

qt.core.qmetaobject.connectslotsbyname: QMetaObject::connectSlotsByName: No matching signal for on_profileBox_currentIndexChanged(QString)

which might have something to do with the issue, although I'm not sure how to interpret that. But this is also reported here #581 and it's not clear to me whether it's the same problem.

Desktop (please complete the following information):

• OS/Distribution: Archlinux
• Version 1.4.0

Fixed in #681.
