This thread is about warehouse application, and not about all application from openrepos.
Openshot have _all suffix, because its archeticture independent application, probably writtent in python. As for dependencies, seems like they are missing, because first packages was from apps4meego and meego OBS server when they were closed, and maybe to all packages was extracted. So you can try to rebuild/port packages from scratch, i.e. from ubuntu sources.
