Hi,
I wonder if anyone can help, I get the following in .xsession-errors

xrdb: cannot run '/lib/cpp -traditional -Dlinux -D__i386__

 -DCLASS_TrueColor_8=36 -DCLASS_StaticGray_8=37'

in the file the above is all one line.
I am running bo. I am sure this message did not appear when I first
installed debian.
Any help appreciated.
