Hi,
When trying to debug a Python program, I get the following
error when trying to set a breakpoint:
0. emaccs -Q &
1. C-x C-f test.py
2. From the menubar: Python->Debugger
Run pdb (like this): python -m pdb test.py
3. Click on "Next Line" so I can see a source line
4. Cick on "Set Breakpoint"
I now get the error:
Wrong type argument: stringp, nil
Turning on `debug-on-error' yields the same results.
However, on the *Messages* buffer there is a little more
information about the error:
gud-format-command: Wrong type argument: stringp, nil
How does one debug this problem further?
Thanks.
