git-gui: Paper bag fix error dialogs opening over the main window

spearce · spearce · commit 85ec3e7778c0 · 2008-02-22T01:35:23.000-05:00
If the main window is the only toplevel we have open then we
don't have a valid grab right now, so we need to assume the
best toplevel to use for the parent is ".".
