The crash is deep inside the webkit core library, so I doubt it is a problem in kdewebkit. If you can reproduce the crash, is it possible you could test it with Arora browser? It happened to me twice but I am unable to reproduce now. Looks like a heisenbug. Another crash, stack probably corrupt, occurred when I closed the browser window: Application: Konqueror (kdeinit4), signal: Segmentation fault Thread 1 (Thread 0x7f33ba31a760 (LWP 14439)): [KCrash Handler] #6 0x00007f33aef5d3da in WebCore::Page::setDefersLoading(bool) () from /usr/lib64/libQtWebKit.so.4 #7 0x00007f33aec63597 in WebCore::ScriptDebugServer::setJavaScriptPaused(WebCore::Page*, bool) () from /usr/lib64/libQtWebKit.so.4 #8 0x00007f33aec63641 in WebCore::ScriptDebugServer::setJavaScriptPaused(WebCore::PageGroup const&, bool) () from /usr/lib64/libQtWebKit.so.4 #9 0x00007f33aec63786 in WebCore::ScriptDebugServer::pauseIfNeeded(WebCore::Page*) () from /usr/lib64/libQtWebKit.so.4 #10 0x00007f33aec63d88 in WebCore::ScriptDebugServer::callEvent(JSC::DebuggerCallFrame const&, long, int) () from /usr/lib64/libQtWebKit.so.4 #11 0x00007f33af2e01e3 in JSC::Interpreter::debug(JSC::ExecState*, JSC::DebugHookID, int, int) () from /usr/lib64/libQtWebKit.so.4 #12 0x00007f3397af9dbc in ??

I was not able to get DrKonqi report it because the stack is apparently damaged. The webinspector causing a crash when you close the Konqueror window while it is being shown is a known issue that has been fixed [1] for an upcoming kwebkitpart 1.2 release. See https://projects.kde.org/projects/extragear/base/kwebkitpart/repository/revisions/67a5a3fbfb7f9470c0038f5f33a192db777f4450 The crash during the javascript debugging session however does seems to be an upstream issue, but since you seem to be using QtWebKit that comes bundled with Qt 4.7.x, which unfortunately is a very old version (v2.0), that issue might be have already been solved in the more recent upstream version as well. BTW, would could you install and see if you can duplicate this crash in the Arora web browser ? If you cannot duplicate the crash with Arora, then most definitely the cause of your crash is the one I fixed by the commit I mentioned in comment #5. Arora does not crash under similar circumstances but I cannot reproduce the scroll crash in Konqueror either so it does not prove anything. (In reply to comment #7) > Arora does not crash under similar circumstances but I cannot reproduce the > scroll crash in Konqueror either so it does not prove anything. "scroll crash" ?? The patch fixes the web inspector causing a crash if konqueror is closed while the web inspector is visible. Is that what you meant ? You cannot reproduce the crash on "close" ?? I cannot reproduce the crash on horizontal scroll. The crash on close reproduces inevitably. As I stated in comment #5, the crash on close is fixed. The other crash I cannot duplicate at all and I can only presume it can be choked up to the fact that a very old version webkit (v2.0.0) is bundled with Qt 4.7.x. Even the recently released standalone update to QtWebKit (v2.1.0) is from last July, over eight months old! Anyhow, it is a QtWebKit issue and as such should be reported at http://trac.webkit.org/wiki/QtWebKitBugs. |
