/usr/local/lib/ikiwiki/plugins/rst and /usr/local/lib/ikiwiki/plugins/proxy.py provoke the following error output during some CGI operations if there is no python3 interpreter available

/usr/bin/env: ‘python3’: No such file or directory

the CGI also sporadically dies (with signal 13, => HTTP error 500). I don't understand why this is sporadic though.

This relates to autosetup python warnings and some other bugs.

This happens even if rst and proxy.py are not active on the wiki (as they aren't, by default).

A hacky quick solution might be to rename rst rst.py and for IkiWiki to avoid scanning plugins that end in .py if they are not enabled.
