paths.xpl breaks on filename containing %20

[sbulka]

We had some images containing spaces, which were automatically translated to %20 in their filenames.
Our pipeline then failed with unknown error.
After renaming %20 to _, the pipeline worked.
Should handle it in the default stylesheet, or at least die with a more useful error message.

Sample filename: 20_Abb.5%20Keramiklibrierung_600_grau.tif

But paths.xpl relies on tr:file-uri, and if I invoke

calabash/calabash.sh xproc-util/file-uri/xpl/file-uri.xpl 'filename=20_Abb.5%20Keramiklibrierung_600_grau.tif'

the result is

<c:result
  local-href="file:/C:/cygwin/home/gerrit/Dev/docx-splitter-frontend/20_Abb.5%20Keramiklibrierung_600_grau.tif"
  lastpath="20_Abb.5%20Keramiklibrierung_600_grau.tif"
  os-path="C:/cygwin/home/gerrit/Dev/docx-splitter-frontend/20_Abb.5 Keramiklibrierung_600_grau.tif"
  cwd="C:/cygwin/home/gerrit/Dev/docx-splitter-frontend/"
  href="file:/C:/cygwin/home/gerrit/Dev/docx-splitter-frontend/20_Abb.5%20Keramiklibrierung_600_grau.tif"/>

which at least in its @os-path attribute contains proper spaces. Maybe you can point me to the pipeline in question in a private message.
