      When I try to run a Qt application which bundles "plugins/platforminputcontexts/libcomposeplatforminputcontextplugin.so" from Qt 5.4.0 on a Linux where Qt 5.4.1 is installed, it crashes on startup. Stacktrace (without symbols) is here http://pastebin.com/vuGanpfT and it points to QPlatformInputContext::staticMetaObject().

      Assuming that the bugfix (https://codereview.qt-project.org/#/c/100511/) introduced in QTBUG-40691 has made it into Qt 5.4.1, is it possible that applications bundling plugins from Qt 5.4.0 (or maybe older) can crash on systems with Qt 5.4.1? Is this crash normal or did the bugfix change introduce binary incompatibility?
