Exceptions not raised from conda-build

What happened?

Under some circumstances, conda-libmamba-solver cannot parse the libmamba exceptions correctly and raises with message "None", which is not useful.

I saw this yesterday with a conda-build run that resulted in conflicts due to a messy local CONDA_BLD_PATH (plenty of competing and outdated packages that should not exist), so it's difficult to reproduce.

I might still be able to cause a conflict we can analyze.
