Comment 1 Tim Flink 2013-09-11 15:08:48 UTC
I attempted to reproduce using the f20 alpha tc5 x64 kde live image. I was able to log in to the fedora wiki and search with google without konqueror crashing

Comment 2 Rex Dieter 2013-09-11 15:10:07 UTC
Any chance of a backtrace or abrt report?

Comment 3 Tim Flink 2013-09-12 08:20:29 UTC
Discussed during the 2013-09-11 Fedora 20 alpha blocker bug review meeting [1].

While not a great situation to be in, this is only affecting ARM and could be fixed with an update post-release as it doesn't affect lives. Rejected as a blocker for F20 alpha but a tested fix would be considered past freeze - accepted as a freeze exception.

I don't see any line numbers listed, incomplete -debuginfo ?

Comment 6 Rex Dieter 2013-09-12 13:55:02 UTC
come to think of it, it may be because we limit debuginfo in qtwebkit packaging, else it is ginormous... :(

Comment 7 Paul Whalen 2013-09-12 15:57:45 UTC
Rex, I installed all -debuginfo packages available. Any recommendations?

Comment 8 Rex Dieter 2013-09-12 16:03:44 UTC
Nothing yet, we'll make-do the best we can with the information available.

Comment 9 Rex Dieter 2013-09-12 16:06:00 UTC
May be relevant,
