[GNC] GTK Inspector blowing up on Mint 20 (was Re: help increasing size of font in GnuCash?)

[Adrien Monteleone]

That didn't get very far. Not sure if this is a GnuCash bug, or an 
Inspector bug:

```
mint at mint:~$ GTK_DEBUG=interactive /usr/bin/gnucash
Found Finance::Quote version 1.49.
**
Gdk:ERROR:../../../../gdk/gdkwindow.c:6530:gdk_window_set_cursor_internal: 
assertion failed: (!cursor || gdk_window_get_display (window) == 
gdk_cursor_get_display (cursor))
Bail out! 
Gdk:ERROR:../../../../gdk/gdkwindow.c:6530:gdk_window_set_cursor_internal: 
assertion failed: (!cursor || gdk_window_get_display (window) == 
gdk_cursor_get_display (cursor))
Aborted (core dumped)
```

GnuCash started as did the inspector, but as soon as GnuCash finished 
loading, the Inspector blew up and spit out the above.

I suspect an Inspector error but it could be from being fed something 
unexpected by GnuCash.

For full disclosure, I'm running this in a live environment, Mint is not 
installed.

Regards,
Adrien
