[SOLVED] Responsive JEM and ja_purity_ii template interference

When I am using ja_puritiy_iii with your JEM Responsive, I get a strange behaviour:
when I click "email to a friend" I get a form who is filled with:

<br /><b>Notice</b>: Trying to get property of non-object in <b>/srv/www/vhosts/mysite.ch/httpdocs/plugins/system/t3/base-bs3/html/com_mailto/mailto/default.php</b> on line <b>41</b><br />

In which view, which link/button do you use to open the form?
I dont't really understand what "email to a friend is"

in eventdetails, category and venuedetail there are in top right buttons with icons. The letter icon is to mail an email to a friend.
in the templates protostar and joomlart ja_simple this works best.
in the template ja_purity_iii I get the error notice!

my bad solution: to disable the file which gives the error (renaming default.php to default.php_

Sorry, but I dont see the problem. The demopage does not show this error. Take a look at the screenshots. Did I tested right?
What happens if you remove JEM-Responsive? Does the error occur?

Hi, thanks
I tested more.
It's not only the interference with JEM RESPONSIVE, but in general: it seems to be an interference between:
ja_purity_iii and JEM.
So I fear joomlart will not be interested to clear this interference, if this problem problem is only with JEM. Because ja_purity_iii is a free template.
(You can say, if this is only a problem of this template with JEM, then it's not interesting).

There was an update of ja_purity_iii to 1.2.3. Which solved this problem!
