Thanks a lot for the detailed analysis. In fact, libhtml-parser-perl has not been rebuilt against the time64_t
Perl package yet [1] which would align with your explanation. I'll try to rebuild the package locally and if
it fixes the problem, I'll binNMU it for powerpc.
Your explanation will enable me to debug future occurrences as I now understand the underlying problem.
Thanks,
Adrian
