Comment 26 for bug 827211

I found the same bug, except it happens to me even on opening the settings page.
My report would be 100% the same as this:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626076

It's also happends with iceweasel.

The workaround mentoined in comments is also worked for me:
Fortunately comment line (#file: file) in default-modules.conf works.

Details of my system:

$ uname -a
Linux zsoltbookmint 3.0.0-1-amd64 #1 SMP Sun Jul 24 02:24:44 UTC 2011 x86_64 GNU/Linux

libgnomevfs2-0 1:2.24.4-1
firefox 5.0-1linuxmint1

If someone need any more details, feel free to ask me for it.
