Okular systematically crashes with one specific pdf file. It's a bus network map that is pretty complex.

The weird thing is that it displays it properly, then segfaults after about a second. It can last longer if I move around / use the GUI.

FYI, the crash doesn't occur with evince (and the same poppler version : 0.20.5).

Here's the backtrace : 
*** Error in `okular': free(): invalid next size (fast): 0x00007fd7c0071c00 ***
