No, www.itavisen.no does it. Not www.vg.no
I get a crash, too. But the backtrace is different so it might be about a different bug. Steps: 1.) http://www.itavisen.no/ 2.) Click on any of the "Lesernes beste nettips" below the KUDOS logo 3.) I ended up on http://www.kudos.no/needCookies.html (not sure whether this is a bug by its own or my setting) 4.) Click on the brower Back button quickly after each other Will add backtrace.
Created attachment 27838 [details] Backtrace
I can't reproduce this bug on openSuSE 11, KDE 4.1.2
Navigating back or forward where www.itavisen.no is the target will cause the crash
Looking at the source, I think maybe it should be two & in this if sentence, it should be a logical AND and not the bit AND operator ? void Collector::markStackObjectsConservatively(void *start, void *end) .......... if ((blocks[block] == blockAddr) & (offset <= lastCellOffset)) { if (((CollectorCell *)x)->u.freeCell.zeroIfFree != 0) { JSCell *imp = reinterpret_cast<JSCell *>(x); if (!imp->marked()) imp->mark(); .........
see also bug #167966 and bug #170185 and bug #173066 They are all dealing with crashes on back/next-navigation.
this bug is still there in release KDE 4.1.3 "release 4.9" same problem with www.imdb.com
