Ugh. Sounds like PyPI was down. But we should silently ignore that.

[ThiefMaster]

We already ignore it as in "we don't show the error dialog if the AJAX request fails. I think this was from one of the error emails.

While there is probably not much benefit in having it in the log either, there is one advantage: There was someone else recently (I think in the forums) who had to configure an HTTP proxy so Indico could make outgoing HTTP requests. He might not have noticed this that early were it not for the failing version check request - and when a request then only fails e.g. when getting an image to convert an abstract to PDF, there wouldn't be a log message at all, and users would wonder why their image fails...

BTW, please make sure to never include your indico_session token when posting error emails. Having this token would allow someone to hijack your session (you might want to logout and login again to invalidate the token you posted here)

I'm just wondering if this won't be too noisy. Maybe we could turn it into a warning instead?
