Steps to Reproduce: 1. Open Okular 2. Edit -> Find... 3. Type a word Actual Results: Nothing found reportedly happens, but only on f18+ (I certainly cannot reproduce on f17)
Some people upstream suspect that this may be a GCC bug, and as GCC is also the main difference between Fedora 17 and 18 (gcc-4.7.0-5.fc17 vs. gcc-4.7.1-5.fc18), it may indeed well be a regression in GCC.
Cannot confirm this on latest rawhide/f18 (on x86_64).
confirmed works ok with okular-4.10.1-1.fc18
