Increase a bit importance since crash.

Miklos: noticing http://cgit.freedesktop.org/libreoffice/core/commit/?id=ad913681c0e0cdaaa706329f518f59ee54b86d43, I thought you might be interested in this one. (didn't say the commit triggered the problem! :-) Just meant you'd perhaps have an idea of the problem)
