[Bug 1058884] Re: Race condition in py_compile corrupts pyc files

Fri Aug 30 00:14:39 UTC 2013

I went through a few crashes with EOFErrors on them on errors.ubuntu.com
today and did not find any with the python packages from -proposed in
their dependencies.  I did this by checking the individual instances of
all the "web_link"s below.

  yeay for automatic bug reporting!

  this is happening pretty regular, I have no idea what's triggering it,
  a cron job maybe?

  if I run it manually, it get:

  ~$ sudo do-release-upgrade
