Binary package hint: unity-2d
This is bug 791213, with a better stack trace (for all threads), and
possibly useful console messages. I produced this by installing all the
debug packages providing symbols referenced in Didier Roche's manual
trace (https://bugs.launchpad.net/ubuntu/+source/unity-
2d/+bug/791213/comments/2), after Cristian Aravena Romero's pointed out
how that trace was incomplete (https://bugs.launchpad.net/ubuntu/+source
/unity-2d/+bug/791213/comments/5).
The trace here is the best I was able to produce (using binary
packages), and is more complete than Didier Roche's manual trace, but
this trace is still not perfect. I think some information may be
destroyed by stack corruption every time this crash occurs. Most
- notably, the following line appears in Didier Roche's manual trace, and
- a corresponding line appears in this trace as well:
+ notably, the line
- #44 0x01c6b2d9 in ?? ()
+ #44 0x01c6b2d9 in ?? ()
+
+ appears in Didier Roche's manual trace, and the corresponding line
+
+ #44 0x063f92d9 in ?? ()
+
+ appears in the trace here.
To produce this, I ran unity-2d-places manually by opening a Terminal
window and running the command "unity-2d-places" (without the quotes).
The following messages were printed immediately:

I waited a couple of minutes to make sure that everything was completely
loaded, then clicked on the home button, and the following messages were
printed, culminating in the crash:
