The first crash occurs in ubuntu-drivers-common.

Locale wrongly configured. Needs to be UTF-8.

[Gaétan QUENTIN (gaetan-quentin)]

NO.

I don't think this is the root problem. There is a file read by software-property* somewhere which is not utf-8 compliant. This problem came after a long working fine system with 16.04. locale didn't changed.

Could it be possible to output in the softawre-properties-tgk* code , the read failure "file name" which is in failure ? Telling it in the output could be helpfull to track problem.
