describe fails

maxima 5.9.2 under win2000

when maxima is run for the first time after
installation, describe works fine.
in later program runs,

? foo

or

describe(foo);

yield the following error message:

Maxima encountered a Lisp error:

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
