[DRE-maint] Bug#610288: thin: ActiveRecord session store doesn't work with Rails

[Faidon Liambotis]

Package: thin
Version: 1.2.4-1
Severity: grave
Tags: patch
Justification: renders package unusable

When using Rails, thin ignores the configuration directive of picking
ActiveRecord for a session store and falls back to a CookieStore instead
(which is limited to 4K among other things).

The bug is reported upstream[1] and the trivial one-line fix made it to
1.2.5. I've patched thin locally with the fix there and I confirm that
it fixes the issue.

The problem appears only with Rails >= 2.3.5 but this is the version
that is present in the archive right now and will be released with
squeeze.

I presume that the biggest use case of thin is hosting Rails
applications, and hence I'm marking this as grave; feel free to
downgrade if you feel differently.

Regards,
Faidon
