--- Comment #5 from Sami Liedes <sliedes cc hut fi> 2010-03-11 22:17:44 --- I take it you can't reproduce this. Ok, I'll run it under valgrind. FWIW I can reproduce it both on my desktop and my laptop (both running Debian unstable on amd64), but even on my laptop, I need to zoom until the page is something like 1600 px wide. Here's the valgrind output. I'll recompile it without optimizations and try to reproduce it then for better traces unless you can figure it out by then, but here's first the valgrind output from the stock (optimized) okular in Debian. >From that it seems to be a read through a null pointer. ==1236== Memcheck, a memory error detector ==1236== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al. ==1236== Using
