[Debian-astro-maintainers] Bug#954121: ftools-fv: Closing fv crashes XWayland and Gnome

[Henry Gebhardt]

Package: ftools-fv
Version: 5.5+dfsg-2
Severity: critical
Tags: upstream
Justification: breaks unrelated software

Dear Maintainer,

I was inspecting the FITS file at
https://github.com/LSSTDESC/NaMaster/blob/master/test/mask.fits . I open the
file on the command line, "fv mask.fits", then open the header (so three
windows are open), then quit the application by pressing the last button on the
main window.

As a result the desktop environment (Gnome as Wayland) crashed, and I am
presented with the GDM login screen.

This is the first time I am using fv on this system.

In the journal I see messages of the form
