Hi everyone, I'm from Qt and working on the bug Steve reported. The Stacktraces
I see here look like 3 completely unrelated problems.
The original issue might be https://bugreports.qt.io/browse/QTBUG-57608
The Fedora Retrace Server stacktrace might be related to
https://bugreports.qt.io/browse/QTBUG-59692
And I am very confident that the crash in
QtWebEngineCore::NetworkDelegateQt::OnBeforeURLRequest is a dereferencing of a
dangling pointer, caused by kontact. You probably use the same
QWebEngineRequestInterceptor for (and make it a child of) multiple
QWebEnginePages so when one of the pages is closed, it deletes the interceptor
and the next navigation accesses the dangling pointer, causing the crash.
Comparing the stacktrace to the 5.6.2 version of network_delegate_qt.cpp, this
seems highly likely.
