thank you

Dear release team & GNOME maintainers,

thank you for making Debian!

I wonder if this bug (#972716) might be worth fixing before the release 
of bulleye. Upstream released a fixed version but a targeted backport 
would also help.
Given that it is quite easy to hit, this will not only render people's 
GNOME desktop unusable but I would consider it very likely to cause 
damage, too, either from exhausting storage or damaging the drives.

Best regards

Thomas
