Here is the stack from the telephony-service crash that is attached.
Looks like thread 1 is the culprit, is using media-hub client, I'm
guessing to play incoming ringtone on incoming call.

Title:
  unity8 crash in image krillin rtm 139

Status in “unity8” package in Ubuntu:
  New

Bug description:
  Earlier today, a few QA folks tested image krillin rtm 138 plus silo
  13, and found that it fixed the unity8 crash from bug 1382595.

  Silo 13 plus silo 10 landed in image 139.

  Now, in image 139, unity8 is crashy again.  Olli mentioned getting two
  crashes within a few minutes, and I got a unity8 crash while trying to
  accept an incoming call.  I'm not sure if it's the same crash as
  before, or if it's a new one.

  Attached is the crash dump I got just after hitting 'accept' for an
  incoming call.  I tried to pre-process it in apport-cli, but it failed
  with "Sorry, the program "unity8" closed unexpectedly  //  Your
  computer does not have enough free memory to automatically analyze the
  problem and send a report to the developers."
