[Touch-packages] [Bug 1514928] Re: ListItem outside ListView segfaults
I confirm the bug. I spent some time debugging it, I found out the following: the main problem is that ItemParentHasChanged arrives to ListItem *after* setSelected is called. That means UCViewItemsAttachedPrivate::get(listItem) returns a QObject(0x0), hence UCViewItemsAttachedPrivate::get(listItem)->addToSelected(q) is called on an uninitialized object. addToSelected then calls selectedList.contains(), but selectedList is an uninitialized object at that point (note: even though it sits on the stack) because it is part of the state of the object UCViewItemsAttachedPrivate, which is uninitialized, and that makes selectedItem.contains() implementation lead to the crash. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1514928 Title: ListItem outside ListView segfaults Status in Canonical System Image: New Status in ubuntu-ui-toolkit package in Ubuntu: Confirmed Bug description: Reproduce: Use the code from the documentation [1] but add selected: true to any ListItem.
