A couple of observations: 1. It seems that the crash occurs only when switching between Video- or Music- lens to any other lens. 2. There are a lot of qt-at-spi warnings related to unsupported events, e.g. ..... unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: QDeclarativeColumn(0x8c50ba8) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: TextCustom_QMLTYPE_29(0x902b8b8) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: TextCustom_QMLTYPE_29(0x90bc010) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: QDeclarativeItem_QML_60(0x90a9578) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: QDeclarativeColumn(0x90cf0a8) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: TextCustom_QMLTYPE_29(0x8ff8718) "" unity-2d-shell: [WARNING] QSpiAccessible::accessibleEvent not handled: "800b" obj: TextCustom_QMLTYPE_29(0x90d9478) " ......
if you look at stacktrace frame for QDeclarativeAccessibilityUpdater::sendGeometryUpdate method call, its 'item' argument corresponds to one of the QDeclarativeColumn objects displayed in qt-at-spi warnings, e.g. #6 0xb6e6b163 in QDeclarativeAccessibilityUpdater::sendGeometryUpdate (this=0x81b4c2c, item=0x90cf0a8) and it's always QDeclarativeColumn for every crash I experienced. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/918566 Title: unity-2d-places crashed with SIGSEGV in QCoreApplication::notifyInternal() To manage notifications about this bug go to: https://bugs.launchpad.net/unity-2d/+bug/918566/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
