FIX: mark + crtl-L -> crash

[Peter Kümmel]

Here a fix for a Status.15x bug:

EDITING
* Open "de_Intro.lyx"; mark first word ("Einführung"); invoke "ert-insert" => 
seg fault

But the patch only fixes the "symptom", out-of-bound access on a array.
Maybe someone who understands this paragraph stuff knows a better solution.
