I can reproduce this behaviour in both Linux and Windows.
wxMaxima gives an error message, which in English should read like
"The generated xml file is corrupted.
Please file a bug report."
and additionally
"Error while reading XML:'mismatched tag' in line 1".
Jean-Claude, can you please file a bug report in wxMaxima?
