Package: iotop
Version: 0.6-24-g733f3f8-1.1
Followup-For: Bug #737043
Dear Maintainer,
I was running the PostgreSQL regression tests, which exercise pg_upgrade
with invalidly-encoded database names to verify the integrity of that code.
I spawned iotop while that was running, and after displaying the screen for a
few iterations, it died with the backtrace I paste below.
I think this is unreasonable and unhelpful; it seems to me that the
correct response to invalid chars in process names in this case is just
to ignore them, maybe print an interrogation point, and move on.
Crashing is entirely a wrong, unhelpful reaction.
Thanks for packaging this otherwise wonderful utility!
