pplatex doesn't parse errors correctly when file:line:error style messages is enabled

[ngirard]

Consider the following minimal document:

\documentclass[11pt]{article}
\begin{document}
\zzz{aa}
\end{document}

When saved as tst.tex and compiled using

pdflatex -interaction=nonstopmode -no-file-line-error *tex ; pplatex -i tst.log

pplatex works as expected and produces

** Error   in ./tst.tex, Line 3: Undefined control sequence \zzz

Result: o) Errors: 1, Warnings: 0, BadBoxes: 0

But when using

pdflatex -interaction=nonstopmode -file-line-error *tex ; pplatex -i tst.log

the error is not reported:

Result: o) Errors: 0, Warnings: 0, BadBoxes: 0
