The workaround is here https://code.launchpad.net/~tpeeters/ubuntu- docviewer-app/bug1577277-workaround/+merge/304561 I did not mark it yet as fixing the bug because the cause needs further investigation. But the workaround will do it now if we need a quick fix. ** Branch linked: lp:~tpeeters/ubuntu-docviewer- app/bug1577277-workaround -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577277 Title: Document Viewer app freezes/crashes on clicking back from pdf files To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1577277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1577277] Re: Document Viewer app freezes/crashes on clicking back from pdf files
Something strange is happening with VerticalView of poppler-qml-plugin.
When destroying the page displaying the PDF, the VerticalView in QML
reports that it is being destroyed (I added Component.onDestruction:
print("destroying VerticalView"), but it is not yet being fully
destroyed, and in C++ when calling .isNull() on the VerticalView, it
appears to return false.
In ucheader.cpp we detect a change in the header visibility (it is made
invisible because it is also being destroyed) which triggers an update
in the flickable margins. We always first check there that the flickable
is still valide using m_flickable.isNull(), which reports that the
flickable is still valid. However, when calling functions on
m_flickable, we get a segfault.
This is weird and requires further investigation. But I will attach a
branch with a workaround for the document viewer.
