Hi There
I’ve found that the Avogadro in OpenSuse’s build service (Science repository, avogadro-1.2.0-4.3.src.rpm) would not work with openbabel-2.4.1-14.1.src.rpm, it would not open any files and finishes “failed message”. Downgrading it to an older version of Avogadro resulted in the same problem.
After I downgraded to openbabel-2.3.1-23.20 it started working, got this package from https://build.opensuse.org/package/show/openSUSE:Leap:42.3/openbabel
hope it helps
