I'm reassigning this back to gnome-shell for now, because we don't know
for sure that this is a lcms2 or colord bug (although it seems likely to at
least be *related to* lcms2 or colord).

Was there a recent upgrade that made GNOME start to crash in this
situation, or has this happened for as long as you have been using
this dock?

If you install the mutter and xterm packages, and create a test user with
something like this in their ~/.xsession:

    #!/bin/sh
    mutter &
    exec xterm

then copy /usr/share/doc/gdm3/examples/custom-x11-session.desktop into
/etc/X11/sessions/, and log in to "Custom X11 session" as that user,
do you get a similar crash when you plug in the dock? If you do, that
would narrow this down quite a lot by eliminating gnome-shell from the
packages we need to consider, and isolating the bug into either mutter
or a library that it uses (such as lcms2 or colord).

(Exit from the xterm to end that session.)
