The following tests are crashing frequently in the debug GTK bots: http/tests/fileapi/create-blob-url-from-data-url.html http/tests/history/back-during-onload-triggered-by-back.html In all those cases (and perhaps some more that I was not able to find) the reasons seems to be the same one, a failing ASSERT in FrameView.cpp:2422: ASSERTION FAILED: !priv->loader->isLoading() ../../Source/WebKit/gtk/webkit/webkitwebdatasource.cpp(86) : void webkit_web_data_source_dispose(GObject*) Here you have the full backtrace: Thread 1 (Thread 25207): #0 0x00002b6849073d1e in webkit_web_data_source_dispose (object=0x18e6800) at ../../Source/WebKit/gtk/webkit/webkitwebdatasource.cpp:86 #1 0x00002b684d4f01ca in g_object_unref (_object=0x18e6800) at /tmp/buildd/glib2.0-2.28.6/./gobject/gobject.c:2697 #2 0x00002b68490428dc in WebKit::DocumentLoader::unrefDataSource (this=0x2b685ae3c4f0) at ../../Source/WebKit/gtk/WebCoreSupport/DocumentLoaderGtk.cpp:122 #3 0x00002b68490427ef in WebKit::DocumentLoader::decreaseLoadCount (this=0x2b685ae3c4f0, identifier=1663) at ../../Source/WebKit/gtk/WebCoreSupport/DocumentLoaderGtk.cpp:105 #4 0x00002b684905a041 in WebKit::FrameLoaderClient::dispatchDidFailLoading (this=0x2b685ad439c0, loader=0x2b685ae3c4f0, identifier=1663, error=...) at ../../Source/WebKit/gtk/WebCoreSupport/FrameLoaderClientGtk.cpp:1171 #5 0x00002b68497177fe in WebCore::ResourceLoadNotifier::didFailToLoad (this=0x2b685ae516c8, loader=0x2b685ae69e30, error=...) at ../../Source/WebCore/loader/ResourceLoadNotifier.cpp:98 #6 0x00002b6849716a6b in WebCore::ResourceLoader::cancel (this=0x2b685ae69e30, error=...) at ../../Source/WebCore/loader/ResourceLoader.cpp:384 #7 0x00002b6849716869 in WebCore::ResourceLoader::cancel (this=0x2b685ae69e30) at ../../Source/WebCore/loader/ResourceLoader.cpp:343 #8 0x00002b68496bd187 in WebCore::cancelAll (loaders=...) at ../../Source/WebCore/loader/DocumentLoader.cpp:69 #9 0x00002b68496c02b2 in WebCore::DocumentLoader::stopLoadingSubresources (this=0x2b685ae3c4f0) at ../../Source/WebCore/loader/DocumentLoader.cpp:758 #10 0x00002b68496be8f7 in WebCore::DocumentLoader::stopLoading (this=0x2b685ae3c4f0) at ../../Source/WebCore/loader/DocumentLoader.cpp:262 #11 0x00002b68496d5263 in WebCore::FrameLoader::stopAllLoaders (this=0x2b685ae514f0, clearProvisionalItemPolicy=WebCore::ShouldClearProvisionalItem) at ../../Source/WebCore/loader/FrameLoader.cpp:1806 #12 0x00002b68496d8a43 in WebCore::FrameLoader::frameDetached (this=0x2b685ae514f0) at ../../Source/WebCore/loader/FrameLoader.cpp:2670 #13 0x00002b684954d5ba in WebCore::HTMLFrameOwnerElement::willRemove (this=0x2b685ae41330) at ../../Source/WebCore/html/HTMLFrameOwnerElement.cpp:58 #14 0x00002b684954cbbf in WebCore::HTMLFrameElementBase::willRemove (this=0x2b685ae41330) at ../../Source/WebCore/html/HTMLFrameElementBase.cpp:280 #15 0x00002b6849358004 in WebCore::willRemoveChild (child=0x2b685ae41330) at ../../Source/WebCore/dom/ContainerNode.cpp:387 #16 0x00002b68493581e4 in WebCore::ContainerNode::removeChild (this=0x2b685ae3c310, oldChild=0x2b685ae41330, ec=@0x7fffefee95cc) at ../../Source/WebCore/dom/ContainerNode.cpp:427 #17 0x00002b68493dcaa1 in WebCore::Node::removeChild (this=0x2b685ae3c310, oldChild=0x2b685ae41330, ec=@0x7fffefee95cc) at ../../Source/WebCore/dom/Node.cpp:659 #18 0x00002b68491bf28a in WebCore::JSNode::removeChild (this=0x2b689c4a5318, exec=0x2b689c0140d0) at ../../Source/WebCore/bindings/js/JSNodeCustom.cpp:172 #19 0x00002b6849e42627 in WebCore::jsNodePrototypeFunctionRemoveChild (exec=0x2b689c0140d0) at DerivedSources/WebCore/JSNode.cpp:493 #20 0x00002b685c0011e8 in ??

Skipped yet another test failing for exactly the same reason: http/tests/history/back-to-post.php http://trac.webkit.org/changeset/88255
(In reply to comment #2) > Skipped yet another test failing for exactly the same reason: > > http/tests/history/back-to-post.php > > http://trac.webkit.org/changeset/88255 We've skipped so many tests for this issue it'd really be a good idea to get to the bottom of it. Likely the assert is misplaced, but perhaps we can look back through the trac to find out when this started happening.
