The info node GDB Graphical Interface File > GDB User Interface Layout
suggests setting the (customizable) variable gdb-show-main non-nil in
order to have the source buffer displayed on startup of M-x gdb. But if
you do this and then run M-x gdb without specifying a file to debug, M-x
gdb doesn't initialize properly, and the *Messages* buffer contains
error in process filter: gud-find-file: Wrong type argument: stringp, nil
I think M-x gdb should just start up normally in this situation, perhaps
with a message that there's no source file.
To reproduce:
emacs -Q
M-: (setq gdb-show-main t) <ret>
M-x gdb <delete any file name in the prompt> <return>

The following patch seems to fix it. OK to apply?
