If the command fails, you simplify have no idea of what happened. For example,
thanks to stdout/stderr, you noticed the warning. Without stdout/stderr, the
warning should be hidden.
webbrowser is already able to detect that GNOME is running and uses gvfs-open
in that case. Maybe we should exchange these two blocks of code to prefer
gvfs-open over xdg-open on GNOME?
# use xdg-open if around
if shutil.which("xdg-open"):
register("xdg-open", None, BackgroundBrowser("xdg-open"))
# The default GNOME3 browser
if "GNOME_DESKTOP_SESSION_ID" in os.environ and shutil.which("gvfs-open"):
register("gvfs-open", None, BackgroundBrowser("gvfs-open"))
Do you get the warning if you use gvfs-open?
