maxima 5.17.1 + wxmaxima 0.7.1



Hello,

I am using maxima with wxmaxima on a Debian lenny system. When doing

load(itensor);

within wxmaxima I get

Maxima encountered a Lisp error:
 Error in SYMBOL-NAME [or a callee]:
"/usr/share/maxima/5.17.1/share/tensor/itensor.lisp" is not of type
SYMBOL.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.

There is no this error when I use maxima in a terminal. Any solutions
besides upgrading wxmaxima to the latest version?
