Bug 494406

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.8) Gecko/2009032600 SUSE/3.0.8-1.1 Firefox/3.0.8

Using tcsh-6.15.00-93.6
If the environment variable LS_COLORS is set to a value that includes 'rs=' then tcsh prints an error and won't start:

Unknown colorls variable `rs'.

If LS_COLORS is not set, or if it does not include an 'rs=' entry, tcsh will start normally.

rpm -q -i tcsh

Summary     : The C SHell
Description :
Tcsh is an enhanced, but completely compatible, version of the Berkeley
UNIX C shell, csh(1). It is a command language interpreter usable as an
interactive login shell and a shell script command processor. It
includes a command-line editor, programmable word completion, spelling
correction, a history mechanism, job control, and a C-like syntax.
