Aha! I have found the Qt bug that corresponds with this issue: https://bugreports.qt.io/browse/QTBUG-36129
This was fixed in 5.3.0 (which is the version Utopic ships with). However, this doesn't help Trusty users since existing applications will fail to work. Is there any chance that this fix could be backported to Trusty? This is the patch that would need to be applied: https://codereview.qt-project.org/#/c/81095/2//ALL,unified -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441961 Title: dataChanged signal cannot be used on ARM under certain conditions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1441961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
