Summary: okularkirigami with Qt 5.9.8
Product: okular
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: okular-de...@kde.org

backtrace
SUMMARY
Okular claims it supports Qt 5.9 yet okularkirigami seems to require at least
Qt 5.10 . After addressing this I observed the attached crash.
This is with the git/master head.
STEPS TO REPRODUCE
1. Apply the QML patches from the attached patch file
2. rebuild and run okularkirigami
3. click the unlabeled lower-right control to open the page selector
4. click it again
OBSERVED RESULT
Crash
EXPECTED RESULT
I suppose the page selector should close again.
SOFTWARE/OS VERSIONS
KDE Frameworks Version: 5.60.0
Qt Version: 5.9.8
ADDITIONAL INFORMATION
The PageItem::paint() method may never be called with a null window() when
using a newer Qt version but given that other member functions check the
property it may be wise to do so here. Idem for the change to
DocumentPrivate::requestDone() (though one may wonder why a null observer would
be held in m_observers).
