NB: the timeout appears to be a global parameter, not something that can be
varied so you cannot have different timeouts on tap-and-hold gestures (on
different objects, for instance) in a single application.
That means it *should* be possible to inject an override that sets the timeout
to some sufficiently long duration so you don't trigger the gesture by accident
but can still trigger it if you want to.
That would be done by a simple call to QTapAndHoldGesture::setTimeout(); a good
place to do that would be in a widget style. Those are typically not very
complicated to build (and distros usually make it easy to install the build
dependency of any of their packages).
@Duncan: in what part of the code did you see the implementation? I put my own
implementation in the KdePlatformTheme class which is one of the rare places
where it gets exposed to just about any Qt application with a GUI. If the
Plasma implementation is in a similar package (the plasma-framework isn't the
most complex or expensive to build) it would be almost just as easy to disable
the feature or set that timeout there.
