To reproduce: 1. Go to http://www.the-lizard-lounge.com/ 2. Click "Web Design" link at bottom of page This crashes with the following abbreviated backtrace: #0 0x01d46d70 in KWQKHTMLPart::generateFrameName (this=0x0) at /Volumes/Big/johnsullivan/ Projects/Labyrinth/WebCore/kwq/KWQKHTMLPart.mm:205 #1 0x01dbc4e8 in KHTMLPart::requestFrameName (this=0x0) at /Volumes/Big/johnsullivan/Projects/ Labyrinth/WebCore/khtml/khtml_part.cpp:1742 #2 0x01d59780 in KWQKHTMLPart::setName (this=0xd96fe00, name=@0xbfffcfd0) at /Volumes/Big/ johnsullivan/Projects/Labyrinth/WebCore/kwq/KWQKHTMLPart.mm:3830 #3 0x01daf4a8 in -[WebCoreBridge setName:] (self=0x22d13490, _cmd=0x90a31188, name=0x22de2c60) at /Volumes/Big/johnsullivan/Projects/Labyrinth/WebCore/kwq/ WebCoreBridge.mm:1627 #4 0x01257880 in -[WebFrame(WebPrivate) _continueLoadRequestAfterNewWindowPolicy:frameName:formState:] (self=0xe132e10, _cmd=0x909da6e8, request=0x22dec3e0, frameName=0x22de2c60, formState=0x0) at /Volumes/ Big/johnsullivan/Projects/Labyrinth/WebKit/WebView.subproj/WebFrame.m:1825 #5 0x0125011c in -[NSObject(WebExtraPerformMethod) performSelector:withObject:withObject:withObject:] (self=0xe132e10, _cmd=0x90a253d0, aSelector=0x909da6e8, object1=0x22dec3e0, object2=0x22de2c60, object3=0x0) at /Volumes/Big/ johnsullivan/Projects/Labyrinth/WebKit/WebView.subproj/WebFrame.m:125 #6 0x01256be8 in -[WebFrame(WebPrivate) _continueAfterNewWindowPolicy:] (self=0xe132e10, _cmd=0x909da638, policy=WebPolicyUse) at /Volumes/Big/johnsullivan/Projects/Labyrinth/WebKit/ WebView.subproj/WebFrame.m:1660 #7 0x012a0af4 in -[WebPolicyDecisionListener _usePolicy:] (self=0x22d82c20, _cmd=0x909feba8, policy=WebPolicyUse) at /Volumes/Big/johnsullivan/Projects/Labyrinth/WebKit/WebView.subproj/ WebPolicyDelegate.m:90 #8 0x012a0bcc in -[WebPolicyDecisionListener use] (self=0x22d82c20, _cmd=0x90a3aa70) at / Volumes/Big/johnsullivan/Projects/Labyrinth/WebKit/WebView.subproj/WebPolicyDelegate.m:106 #9 0x00133268 in -[BrowserWebView informDecisionListener:ofPolicyDecision:] (self=0xe166100, _cmd=0x18fd68, listener=0x22d82c20, decision=PolicyUse) at /Volumes/Big/johnsullivan/Projects/ Labyrinth/WebBrowser/BrowserWebView.m:1435 The immediate cause of the crash is that _bridge is nil in KWQKHTMLPart::generateFrameName. This causes [_bridge generateFrameName] to return nil, which then causes QString::fromNSString() to choke. This seems likely to be fallout from Maciej's recent refactoring of where the frame traversal code lives.

I should explicitly add that this does not occur on released versions of Safari.
