Dear maintainers of gvfs-bin,

I tried now to find out *why* gvfs-open opens everything in the
desktop browser ...

I straced a gvfs-call and the following files (that exist) containing
"mime" or "default" are opened:
  /usr/share//mime/mime.cache
  /home/norbert/.local/share/applications/mimeapps.list
  /usr/share/gnome/applications/mimeinfo.cache
  /usr/share/gnome/applications/defaults.list
  /usr/local/share/applications/mimeinfo.cache
  /usr/local/share/applications/defaults.list
  /usr/share/applications/mimeinfo.cache
all of these when searched for application/pdf give evince.desktop
or a more complete list of pdf viewers. Onl the mime.cache I couldn't
check since it is a binary file.

I don't see why gvfs decides to open that in a file manager. No warning
message, no error message, nothing points to a file manager.
As already mentioned in the bug report, all the xdgg-mime point to
evince.

Inspired by another bug report I was reading I trid that:
$ python -c 'import gio; f = gio.File("file:/home/norbert/foo.pdf");print f.query_default_handler();'

and ....: <gio.unix.DesktopAppInfo at 0x7f73a8e73910: File Manager>

yeah, that is *wrong*

But I have not the faintest idea how to teach this gio gfile gvfs gf*whatever
to use proper things ...

Could the maintainer please enighten me, and maybe many others, too???

Best wishes

Norbert
