Firefox crashes, while opening file downloading dialog

My Firefox crashed, when I pressed Ctrl+Shift+Y. This key combination open "Downloads" dialog. I found, that error message was:

firefox: symbol lookup error: /usr/lib/gnome-vfs-2.0/modules/libfile.so: undefined symbol: gnome_vfs_unescape_string

So, I found solution that helped me and, hope, will help you. Just edit file /etc/gnome-vfs-2.0/modules/default-modules.conf and comment line (write "#" before it): "file:file".
