Installed core 1.0.2-7 now (what's the diff to 1.0.2-6?).
It works again! many thanks for your effort to make it functional again!

One word to dependencies: formerly there was a package called plugins-all or like that which just installed all available plugins and mbarcode itself didn' depend on any plugin. Now some plugins are depended on by mbarcode. Are they really needed? I guess one could use it even without plugin wifi or qrcode, right?

I just uninstalled mbarcode and only left -core and some of the -plugins on my system. Works fine!
