Bug#1012258: diffoscope crashes with IndexError: tuple index out of range

[Chris Lamb]

Hi Sander,

> Using diffoscope to compare two files (tar.gz) diffoscope crashes with the

Thanks for the report. Given that you mention .tar.gz & .mp3 files,
and that diffoscope is crashing within code for comparing Python .pyc
files (!), I suspect what is happening is that diffoscope is not
detecting the filetype correctly. (Still, diffoscope shouldn't be
crashing when encountering an "invalid" .pyc file. In other words,
there is at least one problem here.)

Please could you provide:

  a) The two .tar.gz files in question

and:

  b) The result of running diffoscope and appending "--debug 2>debug.log"
     and attaching the resulting debug.log.

With that, I'm sure I can quite easily diagnose and fix both potential
issues for you.


Regards,
