Auto retried failed nzb downloads

[Sypher]

I was expecting a download the be finished already, but apparently the NZB from the RSS failed.
It might be nice if SABnzbd could auto-retry failed NZB's for X times when it fails to download.

Yes, you can manually re-add it by simply clicking the link. But since I use the RSS feeds for a reason, full automation is preferred.

NZBs that fail because of a clear reason (like report does not exist) and after
multiple timeouts are not automatically retried.
There's no point in hammering sites, it may even get you banned.

We are tightening up the code dealing with NZB retrieval handling
for the next minor release.

The NZB in question was failing with reason: "URL Fetching failed; Unusable NZB file"

The message is a bit.. odd, did it fail to download or did it download and was it an invalid file?
Either way, when I clicked "Try Again" a little while later it worked.

In that case SABnzbd probably got an HTML page instead of the NZB file.
We've seen this happening for a while with nzbmatrix, until they go their act together.
As I said we are looking at improving error recovery.
Not easy because it's hard to outguess malfunctioning NZB sites.
newzbin's API is rock-solid, this much less the case for other sites.
Obviously we've had our share of problematic code too.
