Comment (by rain-undefined):

 Update: this may be related to an earlier ticket
 https://trac.torproject.org/projects/tor/ticket/20884 .

 For me the Tor Browser does not crash, and works happily even though it is
 denied `/etc/machine-id`. It does become unable to communicate with other
 applications using I-Bus (an example being my input method), which I think
 is expected after reading yawning's comment under that ticket.

 And if I include `<abstractions/dbus-session-strict>` (which will permit
 the browser to read `/etc/machine-id`) and `<abstractions/ibus>` in the
 profile, TB will start to work with I-Bus applications again.

 Also, thanks gk & sysrqb for working on this (although i cannot understand
 much yet)
