Hi there, I am building the debug version of Webkit(trunk) on Mac (Version Mac OS X 10.5.4, PPC). I am using the Flash player 10 (Version 10.0.2.26). Attached below is the Stack trace that I am getting. At the same time I can play a Flash movie in Firefox 3, and Safari 3.1.2 with the same version of Flash Player. If I uninstall Flash player 10, and install Flash player 9, everything works just fine. Is anyone else having the same problem. I will appreciate any pointers to solve this issue. Thanks Mugdha. #0 0x92426944 in __pthread_kill () #1 0x924266f8 in pthread_kill () #2 0x951e3424 in Debugger () #3 0x0d278a04 in .objc_class_name_AUGenericViewFactory () #4 0x0d278dcc in NP_Initialize () #5 0x003fbe40 in -[WebNetscapePluginPackage load] (self=0xcae3960, _cmd=0x96c14e04) at /Users/mjain/dev/Webkit/WebKit/mac/Plugins/WebNetscapePluginPackage.m:563 #6 0x003504e4 in -[WebBaseNetscapePluginView initWithFrame:pluginPackage:URL:baseURL:MIMEType:attributeKeys:attributeValues:loadManually:DOMElement:] (self=0xcc8ec70, _cmd=0x465744, frame={origin = {x = 0, y = 0}, size = {width = 1000, height = 300}}, thePluginPackage=0xcae3960, theURL=0xcc109b0, theBaseURL=0xcc8eac0, MIME=0xcc8e370, keys=0xcc8eae0, values=0xcc8ee30, loadManually=0 '\0', anElement=0xcc63080) at /Users/mjain/dev/Webkit/WebKit/mac/Plugins/WebBaseNetscapePluginView.mm:1527 #7 0x00397c3c in WebFrameLoaderClient::createPlugin (this=0xb9dbe0, size=@0xbfffd1f0, element=0xcc64ca0, url=@0xbfffd2a4, paramNames=@0xbfffd444, paramValues=@0xbfffd450, mimeType=@0xbfffd440, loadManually=0) at /Users/mjain/dev/Webkit/WebKit/mac/WebCoreSupport/WebFrameLoaderClient.mm:1321 #8 0x03d0d0c8 in WebCore::FrameLoader::loadPlugin (this=0x7885a24, renderer=0xcc6311c, url=@0xbfffd2a4, mimeType=@0xbfffd440, paramNames=@0xbfffd444, paramValues=@0xbfffd450, useFallback=false) at /Users/mjain/dev/Webkit/WebCore/loader/FrameLoader.cpp:1739 #9 0x03d15a64 in WebCore::FrameLoader::requestObject (this=0x7885a24, renderer=0xcc6311c, url=@0xbfffd43c, frameName=@0xcaa9fa0, mimeType=@0xbfffd440, paramNames=@0xbfffd444, paramValues=@0xbfffd450) at /Users/mjain/dev/Webkit/WebCore/loader/FrameLoader.cpp:1695 #10 0x040fd688 in WebCore::RenderPartObject::updateWidget (this=0xcc6311c, onlyCreateNonNetscapePlugins=false) at /Users/mjain/dev/Webkit/WebCore/rendering/RenderPartObject.cpp:253 #11 0x03d2bfdc in WebCore::FrameView::performPostLayoutTasks (this=0xbae4f0) at /Users/mjain/dev/Webkit/WebCore/page/FrameView.cpp:968 #12 0x03d2cec4 in WebCore::FrameView::layout (this=0xbae4f0, allowSubtree=true) at /Users/mjain/dev/Webkit/WebCore/page/FrameView.cpp:526 #13 0x03cf5084 in WebCore::Frame::forceLayout (this=0xb9d300, allowSubtree=true) at /Users/mjain/dev/Webkit/WebCore/page/Frame.cpp:1337 #14 0x003b47cc in -[WebHTMLView layoutToMinimumPageWidth:maximumPageWidth:adjustingViewSize:] (self=0xbb6e380, _cmd=0x481658, minPageWidth=0, maxPageWidth=0, adjustViewSize=0 '\0') at /Users/mjain/dev/Webkit/WebKit/mac/WebView/WebHTMLView.mm:2817 #15 0x003b4928 in -[WebHTMLView layout] (self=0xbb6e380, _cmd=0x96b7226c) at /Users/mjain/dev/Webkit/WebKit/mac/WebView/WebHTMLView.mm:2834 #16 0x003beae0 in -[WebHTMLView(WebInternal) _layoutIfNeeded] (self=0xbb6e380, _cmd=0x481fbc) at /Users/mjain/dev/Webkit/WebKit/mac/WebView/WebHTMLView.mm:4912 #17 0x003beb34 in -[WebHTMLView(WebInternal) _web_layoutIfNeededRecursive] (self=0xbb6e380, _cmd=0x45b2d4) at /Users/mjain/dev/Webkit/WebKit/mac/WebView/WebHTMLView.mm:4917 #18 0x003ac8fc in -[WebHTMLView(WebPrivate) viewWillDraw] (self=0xbb6e380, _cmd=0x96bc8c30) at /Users/mjain/dev/Webkit/WebKit/mac/WebView/WebHTMLView.mm:1130 #19 0x927cf5c8 in -[NSView viewWillDraw] () #20 0x927cf5c8 in -[NSView viewWillDraw] () #21 0x927cf5c8 in -[NSView viewWillDraw] () #22 0x927cf5c8 in -[NSView viewWillDraw] () #23 0x927cf5c8 in -[NSView viewWillDraw] () #24 0x927cf5c8 in -[NSView viewWillDraw] () #25 0x927cf5c8 in -[NSView viewWillDraw] () #26 0x927cf5c8 in -[NSView viewWillDraw] () #27 0x927ced54 in -[NSView _sendViewWillDrawInRect:] () #28 0x92724538 in -[NSView displayIfNeeded] () #29 0x92724184 in -[NSWindow displayIfNeeded] () #30 0x00021844 in ??
