Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
Seems to be only on French dictionary, the English doesn't crash my firefox.
Also seems linked to /usr/lib/libhunspell-1.2.so.0

Steps to reproduce:

Open Firefox, write in French with grammatical error into a textbox, check a spelling of a word with right click, firefox crash instantly.
