A recent bash*(that's my suspicion)*update to*bash-4.2.10-5.fc16.i686.rpm wiped 'almost clean' my /etc/shells, leaving only nologin and dash behind, breaking pkexec.Anyone else seeing this or am I barking at the wrong tree here?

I have the same update, and /etc/shells is intact:

/home/tkevans $ cat /etc/shells
/sbin/nologin
/bin/dash
/bin/tcsh
/bin/csh
/bin/ksh

Are you certain? I don't see bash here, neither sh.

Perhaps that is what I am seeing in this bugzilla:

I noticed your bug report searching bugzilla. Though, in my case the
brightness keys stopped working in xfce. Specifically, pkexec was
complaining that it couldn't find my $SHELL in system shells.
Still, I'd expect the list of available shells in s-c-u to be read
from /etc/shells directly, so the bug you're seeing seems to be caused
by bash update as well.

Might be related to: https://bugzilla.redhat.com/show_bug.cgi?id=752827

But that would only explain it missing bash, not eating your entire /etc/shells.

What *should* be in /etc/shells (by default)? Reading the comments
gives many examples of bad /etc/shells but no example of a good one.

Then you've read the comments not carefully enough.

The /etc/shells file belongs into the "setup" package and is
modified by shell packages when those are installed/erased.
Therefore you may need to reinstall _any_ shell package on your
system, such as "bash", for it to modify /etc/shells again as a fix.
