Keyboard input issues in plugins (flash)

QWebView* qwv = new QWebView();
qwv->connect(qwv, SIGNAL(destroyed()), qApp, SLOT(quit()));
qwv->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
qwv->load(QUrl("http://www.bubblebox.com/swf6/1380/learn-to-fly.swf"));
qwv->showFullScreen();
qwv->show();
qApp->exec();

wait for flash content to load, poke around and then at some point (where the
plugin expects keyboard input) press a hardware keyboard button.

EXPECTED OUTCOME:
Have the button (un)press event be propagated and processed by the flash app (on libqt4-maemo5 this worked)

ACTUAL OUTCOME:
The flash plugin freezes.

REPRODUCIBILITY:
always, flashlauncher. Occasionally, a "HIM: x11FilterEvent( _HILDON_IM_COM / ) was not handled" message appears on the console.

FlashLauncher from extras-devel exibits this problem well (flashlauncher-experimental which links to libqt4-maemo5 also shows how it used to work).
