This is a hint for people who find they occasionally get View Email request failures in their logs, that look like ...

Nov 24 06:57:03  [ info ] $Fatal Error Details = Array
(
    [ message ] => Could not find valid value for id
    [ code ] =>
)

Nov 24 06:57:03  [ info ] $backTrace = #0 /sites/all/modules/civicrm/CRM/Core/Error.php(300): CRM_Core_Error::backtrace("backTrace", TRUE)

When I check the webserver logs, the requests are coming from IPs that belong to services like "Amazon". The URL being requested has no query parameters (eg, "GET /civicrm/mailing/view HTTP/1.0").

I suspect what is happening is that when recipients of our email use a web-based email client, occasionally those clients follow the links but ignore the arguments. It bothered me that perhaps these messages indicated people were having a bad experience with our site, but I think these are OK.
