The package consists of the latest tarball of the qtwebkit-2.3 branch from gitorious with a single patch that enables settings->acceleratedCompositingEnabled(), taken from the bug https://bugs.webkit.org/show_bug.cgi?id=106892. In attachment I provided backtraces from rekonq (2.0) and arora (0.11.0). They seem to crash because of some fastMalloc call, so this is probably a NULL pointer issue or something in that vicinity. Reverting qtwebkit to qtwebkit 2.2.2 fixes the problem. I am using up-to-date Arch Linux with the following versions of relevant packages: extra/arora 0.11.0-3 community/rekonq 2.0-2 extra/qtwebkit 2.3git20130115-1 extra/qt 4.8.4-1 808472 1 183001 brcha 2013-01-16 10:03:11 -0800 Created attachment 183001 Output from the crashing arora 809795 2 benjamin 2013-01-17 14:34:23 -0800 The crashlog are useless because they are not symbolicated. Can you please attach: -Disassembly at the position of the crash. -Symbolicated crash logs. 811454 3 allan.jensen 2013-01-19 13:16:49 -0800 The backtraces are not very helpfull, but this bug could be the same as https://bugs.webkit.org/show_bug.cgi?id=104525, in which case it should be solved in the latest version of qtwebkit-2.3 817183 4 me 2013-01-26 07:14:11 -0800 On Arch Linux the user who reported this bug solved building qtwebkit with --no-sse2 825423 5 allan.jensen 2013-02-05 06:00:54 -0800 Thank. I will close the bug assuming it was a problem with wrong instruction set then. 183000 2013-01-16 10:02:33 -0800 2013-01-16 10:02:33 -0800 Output from the crashing rekonq rekonq-crash.txt text/plain
