reproduced on demo: One of parameters (value: ) is not of the type Integer

[sonicthoughts]

incomplete urls like: "http://d45.demo.civicrm.org/civicrm/profile/create?" generate an error:

Sorry but we are not able to provide this at the moment.
One of parameters (value: ) is not of the type Integer

There are many examples of this - often generated by a bot (in this case google.)

It may seem inocuous but I'm struggling with a very real issue that only affects iphone / ios 8.x and civicrm registrations that also generates this (somewhat cryptic) error.

Parsing the logs to distinguish bot errors vs. real errors is quite tedious at best.  Is there a better way to handle these unexpected edge cases and possibly distinguish between bots vs. registration workflow errors???

Here is backtrace:
