SUMMARY

When libkxmlgui gets loaded into a non-kde qt app it may mess up application's shortcut framework. This happens because libkxmlgui installs[1] an event filter, which tries to handle shortcuts on its own. Besides it's a quiet dirty practice in general to mess with others global objects with upon lib bootstrap, there are some legit reasons when a non-kde app may load a kde library. i.e. that may happen because the app depends upon a library with optional kde support or via Qt plugin system.

The later one is what exactly happened in freecad[2].

So could you please change the libkxmlgui behaviour so it won't install the event filter on library load or at least do it just for kde apps?
