[Sugar-devel] Debian Advocacy Update - Errors in Calculate on Debian Bullseye

Some of what Shaan has seen on Debian Testing and Saumya has
reproduced on Ubuntu 20.04 is most likely caused by the newer version
of GTK, but neither of you reported the version of GTK.

Debian stable has GTK 3.24.5

Ubuntu 20.04 has GTK 3.24.18

Debian unstable has GTK 3.24.20

You should look at the release notes for GTK between 3.24.5 and
3.24.20.

By the way, "Don't know color" is in GTK 3.24.18 source code seven
times, in four different widget implementations.  You will need to
find which widget reported this.  Also, why is it that a string value
has what looks like source code; perhaps a Gdk.Color has been coerced
to string by mistake.

@Saumya, please don't open issues if you plan to solve the errors.  It
is a waste of notifications and achieves nothing.  Just open pull
requests, one per problem.
