This is a symptom of using Emacs 19.xx with perldb.el which was originally made
for emacs version 18.xx.  You can either install the emacs19 replacement for
perldb that hooks it in with GUD (grand unified debugger), or apply the patches
that I picked off of the net (I use the perldb replacement that uses GUD
myself):

XHere are my patches to perldb.el (the perl debugger mode that comes
Xwith perl 4.0xx).  Basically, all I've done is to hack perldb.el to
Xuse comint.el stuff rather than the old shell.el stuff (i.e. change
Xshell-mode-map to comint-mode-map).
X
XI've been using my patched version without problem, but if anyone sees
Xsomething I've missed, please post or send e-mail.
X
X				Thanks,
X						Dave
