P2: Important Description
Scenario:
- I have a report being shown in a QWebEngineView
- In the toolbar I add forward and back buttons:
mToolBar->addAction( page->action( QWebEnginePage::Back ) ); mToolBar->addAction( page->action( QWebEnginePage::Forward ) );
If I:
- Click a link in my report to jump within the report
- Use the "back" button
On 5.11, it works as expected and I go back to my previous spot.
On 5.12 (SHA: 7156b837104ed9457214c60d411bba2861247ff8) I get a blank page and this in the console:
[95800:775:1113/063049.838501:FATAL:content_settings_observer_qt.cpp(110)] Check failed: frame->GetDocument().GetSecurityOrigin().ToString() == "null" || !url.SchemeIs(url::kDataScheme). 0 QtWebEngineCore_debug 0x0000000114805eee base::debug::StackTrace::StackTrace(unsigned long) + 174 1 QtWebEngineCore_debug 0x0000000114805f4d base::debug::StackTrace::StackTrace(unsigned long) + 29 2 QtWebEngineCore_debug 0x000000011447b14c base::debug::StackTrace::StackTrace() + 28 3 QtWebEngineCore_debug 0x00000001144d595f logging::LogMessage::~LogMessage() + 479 4 QtWebEngineCore_debug 0x00000001144c5675 logging::LogMessage::~LogMessage() + 21 5 QtWebEngineCore_debug 0x000000010d2bab2c QtWebEngineCore::ContentSettingsObserverQt::DidCommitProvisionalLoad(bool, bool) + 508 6 QtWebEngineCore_debug 0x000000011adad24a content::RenderFrameImpl::NotifyObserversOfNavigationCommit(bool, bool) + 442 7 QtWebEngineCore_debug 0x000000011adad392 content::RenderFrameImpl::UpdateStateForCommit(blink::WebHistoryItem const&, blink::WebHistoryCommitType) + 258 8 QtWebEngineCore_debug 0x000000011ad9979f content::RenderFrameImpl::DidCommitNavigationInternal(blink::WebHistoryItem const&, blink::WebHistoryCommitType, bool, mojo::InterfaceRequest<service_manager::mojom::InterfaceProvider>) + 255 9 QtWebEngineCore_debug 0x000000011ad9e474 content::RenderFrameImpl::DidFinishSameDocumentNavigation(blink::WebHistoryItem const&, blink::WebHistoryCommitType, bool) + 1124 10 QtWebEngineCore_debug 0x000000011ad9e721 non-virtual thunk to content::RenderFrameImpl::DidFinishSameDocumentNavigation(blink::WebHistoryItem const&, blink::WebHistoryCommitType, bool) + 65 11 QtWebEngineCore_debug 0x00000001196039a0 blink::LocalFrameClientImpl::DidFinishSameDocumentNavigation(blink::HistoryItem*, blink::WebHistoryCommitType, bool) + 130 ...
This lead me to ContentSettingsObserverQt::DidCommitProvisionalLoad which has the comment:
// If we start failing this DCHECK, please makes sure we don't regress // this bug: http://code.google.com/p/chromium/issues/detail?id=79304
I can try to make a small example if the problem is not obvious from the report.
