[Grok-dev] Paste server gives less (than) useful error messages for TAL errors

[Thibaud Morel l'Horset]

I've definitely witnessed this also. The problem is that it doesn't tell you
which file is generating the problem so if you've edited a bunch of
templates it can sometimes take a little while to find where the problem is.

Sample error:

2009-06-15 10:01:58,360 ERROR [SiteError]
