Mars and Saturn are displayed below the horizon although both planets are visible in the night sky.  Checks with two other sources verify the proper positions of these planets.

I can't confirm this.  Can you please provide more details?
I have set the location to Bellvue, WA and the local time to 2006-02-22 
22:01:29.  Mars and Saturn are both up in my view.  Their Alt/Az 
coordinates are:

Mars:
Az:  264:45:59
Alt: +35:46:37

Saturn:
Az:  165:41:25
Alt: +61:16:54

I now understand what is happening.  If the "Toggle Solar System" button is 
off and the user attempts to "Find" a solar system object the RA and Dec 
default to 0h 0m 0s and 0 0' 0".  Not necessarily a bug, perhaps an 
inconsistency.

Tnx,
John

I just found this bug today. Yes it is a bug, not an inconsistency. Saying a planet is in a wrong location is definitely a bug.

I found the bug looking up comet Holmes, followed by Saturn. Same issue. I had the "Toggle Solar System" button off, and looked up the comet. KStars reported the wrong location. I eventually discovered that when I turned on "Toggle Solar System", it reported the correct location.

By the way, I found this bug in KStars version 1.2.5. I'm running it on Ubuntu Feisty. I'm located in Melbourne, Australia.

Fixing bug #122528.  Now you can center & track on solar system
bodies, even when they are not being drawn.  The centered body remains
invisible but does get a name label.

The drawback from this fix is that users can no longer attempt to save
CPU cycles by turning off solar system bodies; their positions will
still get updated, even when invisible.  Still, that's better than
centering on a null position when the user tries to center on a real
body.
