g_uri_join_internal assertion error on Uri::build

[d47081]

Not sure if this is bug,

Uri::build(
    UriFlags::NONE,
    "gemini",
    None,
    Some("tlgs.one"),
    -1,
    "search",  // < requires slash at begin (e.g. /search)
    Some(&Uri::escape_string(query, None, false)),
    None,
)

GLib-CRITICAL **: 08:37:15.596: g_uri_join_internal: assertion 'host == NULL || (path[0] == '\0' || path[0] == '/')' failed
thread 'main' panicked

Only if the begining slash not provided for path

package = "gtk4"
version = "0.9.4"

The above code is not complete (what's query?) and does not panic by itself either when fixing that. Please provide complete testcases in the future.

I assume the reason why it panics for you is that you try to use the Display impl of glib::Uri? That indeed panics and I think this can be considered a bug in GLib. Please report it over there: https://gitlab.gnome.org/GNOME/glib/-/issues/new

g_uri_to_string() claims to never return NULL and g_uri_build() neither, and this constraint for the path is not documented anywhere. Unclear what the correct way forward is, but something needs to be fixed and if it's the documentation.

Please add a comment here with the link to the issue you created for future reference, thanks!
