OK. For the record, it's not an assumption. Catching TypeError is a way to deal with the fact that there were two versions of this function around. The version of Vte in bionic, because of the MIR team's refusal to let us have PCRE 2 in main, accidentally had an API break relative to the same version released upstream. If you wanted your code to work with the same upstream version of Vte on Ubuntu and non-Ubuntu you had to deal with this.
