...and this is all due to kxmlgui, apparently, which we of course do not even use :). http://lxr.kde.org/source/frameworks/kxmlgui/src/kcheckaccelerators.cpp This looks horrible. It installs an eventfilter on the application(!) and for every QEvent::Resize AND QEvent::LayoutRequest (and only god knows why resize events are prone to alter accelerators) of _any_ widget (all!) restarts a timer (and on window de/activation and some other stuff) Christoph, it reads from a "Development" group - could it be that this is accidentally opt-out (ie. "AutoCheckAccelerators" should default to false)? Otherwise I assume "AutoCheckAccelerators" should default to some application property (and the code streamlined a bit ;-) *** This bug has been marked as a duplicate of bug 337491 *** Git commit 9847606f232d01dd1ac6120579f2f2e90ea9bb1e by Jan Kundrát, on behalf of Roland Pallai. Committed on 02/11/2017 at 19:20. Pushed by gerrit into branch 'master'. Do not add ampersands on address completion Using qaction->data() instead of text() because the latter may (and will) be tampered by Qt (with ampersands).

TL;DR: kwidgetsaddons' KAcceleratorManager injects accelerators to all buttons, unconditionally. Alt-E is a shortcut for € in Czech layout. If I confuse my layouts and want to type €, my e-mail gets sent. Happened to me twice in a row. Setting the shortcut to an empty QKeySequence() in the widget's ctor doesn't help :(. This happens on Plasma5 which injects that kwidgetsaddons plugin into Qt upon install, and this plugin gets loaded automagically upon app startup, apparently. I think that eventFilter looks like a hammer big enough to fix this thing, but it will still result in the an underscore shown in the button's text, which might be confusing. Unconditionally depending on KWIdgetsAddons so that one can call KAcceleratorManager::setNoAccel is a no-no from my point of view. Should we maybe dlopen() that plugin, or something? This is crazy.
