Valgrind doesn't seem to find anything special, and it prevents the glibc
detected abort.
I have also noticed that Okular::Part works, for example, opening the same pdf
in Kile's embedded viewer doesn't produce any crash.

I tried downgrading libpoppler to 0.12.0 (the only version readily available
with packages) and it effectively prevents crashing, but also prevents any
rendering (i.e. I see only white pages) :) 

Here is what glibc finds:

*** glibc detected *** okular: free(): invalid pointer: 0xb1010008 ***
