The string in question is correctly wrapped with the _ method, the file containing it is plugins/backend_info.py. However, I just noticed it's not included in po/POTFILES.in, meaning it's not getting processed by intltool, so the string is not extracted and marked as translatable.
Thanks for finding this bug!

I'll propose a fix in a moment.
