can you reproduce under valgrind? Have you recomplied everything? this seems like a case of miscompilation as it's crashing on QString destructor
I will try with valgrind. I recompiled qt and deleted old folder before install. For KDE I am using kdesvn-build. And today with param --refresh-build. Last time when I tried use valgrind okular was very slow and I weren't able to reproduce.
Just tried with valgrind, but no luck not reproducible. Let say very slow in valgrind to reproduce. Any other idea?
Just to be sure i understand it right. You say you already recompiled Okular after installing qt, right? Also, can you reproduce the crash "at will"? Or happens randomly from time to time?
I can generate crash when I open PDF and press Page Down. Its crashes after 5 sec or let say 20 pages (approx). I recompiled okular of course. Today I will try clean build and try reproduce. We will see
