Player UI fails to load

[hussainaljamri]

Every time I open the app it throws this message (this is from terminal)

QCommandLineParser: option not defined: "__dummy__"
QCommandLineParser: option not defined: "__dummy__"
QCommandLineParser: option not defined: "__dummy__"
QCommandLineParser: option not defined: "__dummy__"
file:///usr/share/bomi/skins/Tethys/bomi.qml:9:1: Type B.AppWithDock unavailable 
     B.AppWithDock { 
     ^
file:///usr/share/bomi/imports/bomi/AppWithDock.qml:15:5: Type Player unavailable 
         Player { 
         ^
file:///usr/share/bomi/imports/bomi/Player.qml:150:9: Type PlayInfoView unavailable 
             PlayInfoView { } 
             ^
file:///usr/share/bomi/imports/bomi/PlayInfoView.qml:22:9: PlayInfoText is not a type 
             PlayInfoText { content: engine.media.name } 
             ^

It also happens every time I reload the theme (any theme)

files do get opened, but videos aren't displayed (because the UI doesn't load?)

I've had this problem for about a year, but someone else reported it much earlier here

Any Ideas?
