Hola Maximiliano,

writing "crash" was only a way to describe that there is a breakage. It
was not meant as 'severity description' ...

The patch works for adding files but now I get zip-archives that I cannot
open with 'unzip'-command:

$ unzip test.txt.zip
Archive:  test.txt.zip
  End-of-central-directory signature not found.  Either this file is not a
zipfile, or it constitutes one disk of a multi-part archive.  In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of test.txt.zip or
        test.txt.zip.zip, and cannot find test.txt.zip.ZIP, period.

Many thanks anyway and sunny greetings,

Joachim
