[PATCH] gnu: Add python-pyxdg.

[-- Attachment #1: Type: text/plain, Size: 376 bytes --]

Hi Guix,

I placed python-pyxdg in the freedesktop module because it fits there
and because it allows me to avoid a circular dependency.

One of the tests is failing.  I do not know why a PNG image is detected
as 'x-apple-ios-png' rather than the expected 'png', but I suspect it's
a problem in "shared-mime-info".  I made the check phase return #t to
avoid a build failure.

Weird.  Normally setting XDG_DATA_DIRS as you did is all it takes, AIUI.

It would be even better to somehow adjust the test files to skip this
one, but if that’s too much burden, I’m fine with this approach.

Missing period.  Also, I would make it:

  ... standards in Python: Base Directory, Menu, Desktop Entry, Icon
  Theme, Recent File, and Shared-MIME-Database.

v2.0-only?

Otherwise LGTM.

Thank you!
