XAppIconChooserDialog: Subclass GtkDialog, not XAppGtkWindow.

mtwebster · mtwebster · commit 27f11087463e · 2026-01-10T14:10:57.000-05:00
The way we implement dialog.run() was causing issues when spawned
from another dialog with its own event loop.

This lets us rely on GtkDialog's handling for this, and allows us
to run it non-blocking, and have a 'response' signal like any other
dialog.
