2006-11-02 10:08:53 Ryan Nielsen: I have NNW 3.0d6 set to show my news in the Combined View, which renders all of the news items on a single web page. Often on current Leopard builds (ever since the last WebKit submission), NNW will crash when I click on a news item. Here's the crashing thread's back trace and I've attached a crash log.

Have not been able to reproduce in Leopard 9A300. 2006-11-05 18:40:20 Eric Christopher: I was seeing this in NewsFire and can reproduce in 9A300. 2006-11-06 00:44:36 Ryan Nielsen: I can repro on demand if someone would like to look @ one of my machines. The trick is to use the combined view (ctrl-3 or View->Layout->Combined) when viewing articles. Then all you need to do is click on the headlines for two articles. 2006-11-06 15:25:50 Brady Eidson: Ryan - thanks for the clarified steps. Using them I got the crash in the debugger. Taking a look... 2006-11-06 15:27:24 Brady Eidson: BTW, to clarify, I got it with ToT sources on Tiger, so it's not Leopard specific 2006-11-14 10:54:05 Stephanie Lewis: Safari BRB Reviewed 2006-12-22 17:09:12 Brady Eidson: I'm finally getting to this one - for some, inexplicable reason my ability to repro has gone away. Specifically, I can no longer activate the combined view via the menu or Command-3... ugh 2006-12-22 17:11:36 Brady Eidson: Getting CrashTracer reports for this in higher-than-expected volumes... Need to regain my ability to repro! I was using 3.0d7, I will try a different version 2006-12-22 17:13:02 Brady Eidson: Wiping prefs worked (what a shocker...) <rdar://problem/4816376>
