Critical messages on application exit

[Saiful B Khan <saifulbkhan gmail com>]

Hello,

I am using gspell for my GTK application written in PyGObject. It works as expected

for the most part. But when the application exits, for each GtkTextView that had a
GspellTextVIew attached, it spews this following critical error message:

gspell-CRITICAL **: _gspell_inline_checker_text_buffer_detach_view: assertion 'GTK_IS_TEXT_VIEW (view)' failed

I am using a subclass of GtkSourceView for my work. My GObject C is not strong

but I think this subclass should still pass the `GTK_IS_TEXT_VIEW` check. The code
for setting up spell checking in my application is:

    spell_checker = Gspell.TextView.get_from_gtk_text_view(self)
    spell_checker.basic_setup()

I think this is the simplest way of doing it, right? Because spell checking and other
features work just fine (more efficient than GtkSpell, might I add).

It could be that there is nothing wrong with gspell but that my SourceView
objects are getting garbage collected before the spell checker has a chance to
detach itself. I don't know if this makes sense for introspection keybindings.

Either way, I felt that I should notify the developers of gspell about this.

Thanks,
