eben@cerberus:~$ sudo file /root/.synaptic/tmp/tmp_sh

/root/.synaptic/tmp/tmp_sh: PNG image data, 825 x 861, 8-bit/color RGBA,
non-interlaced

I asked for a screenshot of some package, and that appears to be it.  As to

It's only a warning so not critical to fix, so I guess I have time to try
non-destructive means of making it not happen.  Thanks.
