Comment 8 for bug 559881

@Chris Coulson,
I have not tested your built of nss 3.12.6-0ubuntu0.9.10.2 (#7) because i do not like adding any other repos except the official ubuntu ones on the laptop i had the error on.

But as far as the only real change is in signing the libnssdbm3.so using shlibsign I upgraded back the:
libnss3-1d to 3.12.6-0ubuntu0.9.10.1
xulrunner-1.9.1-gnome-support to 1.9.1.9+nobinonly-0ubuntu0.9.10.1
xulrunner-1.9.1 to 1.9.1.9+nobinonly-0ubuntu0.9.10.1
And signed the library, so the bug is gone now.

For those of you who do not want to add the Mozilla Security Team PPA and would like to wait untill official fix is released do the following:
1. Upgrade back your libnss3-1d, xulrunner-1.9.1-gnome-support, xulrunner-1.9.1 to the versions i mention above.
2. apt-get install libnss3-tools
3. sudo shlibsign -v -i /usr/lib/nss/libnssdbm3.so

And the bug should be gone.
