Dear Maintainer,

The xdg-open viewer is broken with show(), I can’t open the image in Firefox:
it complains that the image does not exist. I checked in /tmp/user/me/: the
temporary image actually does not exist.
I used to use the display viewer before, it was automatic but now, it seems
that PIL wants the xdg-open viewer before the display viewer. Maybe a check has
been failed?

Yours,
n.
