After reading some more I now believe this is a bug in lxpolkit and filed
a bug report. The mate and Gnome polkit agents deliver the expected 126
exit code when login is cancelled (though the lxqt counterpart, not much
surprisingly, also gives a 127, as does the KDE agent (but bugs in KDE
never surprise me much either)).
For now I guess I will have to settle with a somewhat ambiguous error
message, like "No user-agent running or login was cancelled" :)
