Check GET values are set before using

Great extension but I'm getting the following error on my homepage: Notice: Undefined index: route in /home/wwwridem/public_html/catalog/model/tool/piwik.php on line 218 

The GET variable 'route' is used before checking it is set. This only causes a PHP 'notice' so shouldnt affect operation, however would be good coding practice to solve. Also noticed in my logs other places where this is happening, so look at the other places where this may be happening aswell.

Second user reported within a few hours of first, and saying that it stops homepage loading - think opencart may produce an error on loading for PHP 'notices' by default. Can turn off by changing the lines in the php.ini file;

;display_errors = 1;
;error_reporting = E_ALL; 

However not a good fix - better to remove the cause.

Another user has reported.

Previous comment not completely correct as the PHP error handling is overwritten by Opencart. error handling is instead set in the OC admin at system>settings>server>Display Errors: which can be set to 'no'.

Definitely better to fix the root cause though! Priority fix for next release.

Comment on opencart.com ;

@InaneCoding: this should fix it
edit the file cataolog/model/tool/piwik.php on line 218 and change this

if ($this->request->get['route'] == "product/search") {

to this

if(isset($this->request->get['route']) && $this->request->get['route']=='product/search'){

That should do the trick

Another user reported a "Error code: ERR_CONTENT_DECODING_FAILED" error which stops the homepage from loading (other pages okay). After looking at users logs, they have the same PHP notice on line 218 and a google search suggests an opencart bug causes this to appear as a decoding error - so this is probably the same issue.
