[raflik]

Os: intrepid
winbind: 2:3.2.3-1ubuntu3.4
opera: 9.64.2480.gcc4.qt3

I opened a webpage in opera and I got:

It ends with single "b".

I had similar issues with firefox, galeon, epiphany,... Unfortunately this error is not deterministically reproducible.

My nsswitch.conf:

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
