Comment 7 for bug 1781906

Ah, missing thing from the irc log:

$ sudo /usr/lib/snapd/snap-update-ns telegram-desktop
2018/09/27 13:08:53.110962 main.go:192: cannot change mount namespace of snap "telegram-desktop" according to change mount (/snap/gtk-common-themes/701/share/icons/Suru /snap/telegram-desktop/281/usr/share/icons/Suru none bind,ro 0 0): cannot use "/snap/gtk-common-themes/701/share/icons/Suru" as bind-mount source: not a directory

This is probably the issue, as per:

$ ls -l /snap/gtk-common-themes/701/share/icons/Suru
lrwxrwxrwx 1 root root 12 Sep 11 16:56 /snap/gtk-common-themes/701/share/icons/Suru -> communitheme
