Has anyone looked into it? I have the same issue when I try to profile the memory of a possibly leaking python process.

I think this might be due to a lack of python debugging info. What distro are you on? Can you make sure you have the python-debuginfo (or whatever it's called on your distro) is installed.

I was on a Linux version 3.2.0-60-generic (Ubuntu/Linaro 4.6.3-1ubuntu5). I cannot find any packet like in the standard packet list only something equivalent like pdb. I see the error raises from an incomplete markup in the urwid lib.

Do you have the python-dbg package installed?
