Nicolas:

Yes, `(setq-default cache-long-scans nil)` does indeed fix the problem.  In a version of Emacs Trunk built on October 5, 2013, the default value for `cache-long-scans` is `nil`.  In the recent version of Emacs Trunk built on December 23, 2013, the default value for `cache-long-scans` is `t`.

I would suspect that anyone who uses `org-capture` will have significant problems performing various operations on the `org-agenda-files` subsequent to the initial call.  So my recommendation would be that the Emacs team return the default value of `cache-long-scans` to `nil`; or, fix it somehow so that it doesn't interfere with popular functions like `re-search-forward` and `re-search-backward` after calling `org-capture`.

Thank you very much for your hard work tracking down the issue.

Keith
