Title:
Crash when having multiple QQuickViews in a row
Status in Canonical System Image:
Fix Committed
Status in ubuntu-ui-toolkit package in Ubuntu:
Fix Released
Bug description:
This crash has started with Qt 5.5.1 that is more strict with sharing
objects between qml engines.
My guess it is something wrong with the theming engine that seems to
be a singleton for all qml engines.
When running the example that i will attach with
QV4_FORCE_INTERPRETER=1 QV4_MM_AGGRESSIVE_GC=1 ./borrame3
in xenial i get
$ QV4_FORCE_INTERPRETER=1 QV4_MM_AGGRESSIVE_GC=1 ./borrame3
A
B
QMetaProperty::read: Unable to handle unregistered datatype
'PaletteValues_QMLTYPE_2*' for property 'Palette_QMLTYPE_3::selected'
QMetaProperty::read: Unable to handle unregistered datatype
'PaletteValues_QMLTYPE_2*' for property 'Palette_QMLTYPE_3::selected'
QMetaProperty::read: Unable to handle unregistered datatype

Segmentation fault
while vivid+overlay (has qt 5.4) gets me
