Bug#1148747: libmutter-18-0: Copying ~200 MB crashes the compositor

[Julien Palard]

Package: libmutter-18-0
Version: 50.5-1
Severity: important
X-Debbugs-Cc: julien at palard.fr

Dear Maintainer,

Using the following command:

    yes | head -n 100000000 | wl-copy

Or any variation on copying > 200 MB immediatly crashes the wayland compositor.

I discovered this while editing a file with emacs-pgtk: using C-w on a
way-too-big selection (>200MB of text) leads to the exact same crash.
