Yes, %.100s may avoid a crash after the buffer overflow on the string formatting, but it may quickly crash on another instruction. I don't think that you should limit the error message length to protect Python against buffer overflow. A buffer overflow can corrupt everything, and we should fix the buffer overflow instead :-)

You have debuggers like gdb for that.
