What is the value of Vload_source_file_function?  If it's
load-with-code-conversion (as I think it should be), then either add
(message foo) printouts in load-with-code-conversion and see what
happens there, or put a breakpoint in Finsert_file_contents, which
load-with-code-conversion eventually calls, and see why that fails.

If this is after you invoked Emacs from GDB (as opposed to attaching
to a running program), then I guess it's a bug in that old port of GDB
you are using.  It works for me in v7.2.

Anyway, you can use this less convenient method instead:

 (gdb) p file
 (gdb) xstring

(This assumes that `file' is a Lisp string.  There's `xtype' to show
the type.)
