TOPIC: Error Log - PHP Warning...

Hi,

After some complaints on my site performance (probably nothing to do with DT Reg at all) I've got into the habit of checking my server error logs... I'm seeing this from time to time as one of the entries:

PHP Warning: key() [<a href='function.key'>function.key]: Passed variable is not an array or object in /home/active/public_html/components/com_dtregister/controllers/validate.php on line 109

Anything to worry about? Does it give enough info to identify and fix any issue - or is it too general to assist in any bug squashing?

Thanks! (oh yes, I'm on latest version - at time of writing - both J1.7 and DTReg)
