I am not certain, but you may be able to do this with fl_set_object_prehandler(). You can set a prehandler for your browser and check to see if the xevent is a mouse wheel button event. If it is then return FL_PREEMPT from the prehandler, and that should prevent the event from reaching the browser.

Documentation is here:

It's weird that it crashes, though. When you say it only happens in browsers with a lot of items, how many items is "a lot"?
