Comment(by dilinger):

 Looking at dmesg.out, it's pretty clear that this is an OOM (potentially
 triggered by libertas failures?)

 {{{

 [52721.720011] libertas: tx watch dog timeout

 In the messages file, you'll see lots of errors from NetworkManager.  So,
 taking a wild guess, I'd suspect either:
 a) Chat is unable to access the network, and procceeds to spin/allocate
 lots of memory until the OOM killer kills it, or
 b) libertas errors are causing NM to get confused, at which point NM is
 spinning/allocating lots of memory until the OOM killer kills it (or it
 crashes).
