And import_logs fails because of this PHP warning (as it makes sure the response is a GIF file).

Using Piwik 1.9.1. To reproduce:

curl http://localhost/piwik.php --data '{"requests": ["1", "cdt": "2012-10-10 15:15:52", "urlref": "", "dp": "1", "url": "[]({"apiv":)=foo", "cip": "", "idsite": 42, "rec": "1", "bots": "1", "ua": ""}], "token_auth": "foo"}'

See the URL? The '[]' is triggering the bug. Removing it makes the bug go away.

Sure, I can hide PHP warnings, but it would be nice to handle this properly as we cannot expect our users to hide warnings.


Can you please try with latest beta (which is morestable than 1.9.1):

I cant reproduce this bug with latest beta but if you still can let me know or re-open the ticket.


Yes, I can reproduce it with 1.9.3-b3:

<b>Warning</b>: urldecode() expects parameter 1 to be string, array given in <b>/data/www/piwik2/core/Tracker/Action.php</b> on line <b>977</b>


(In [7411]) Fixes #3523 Please confirm the fix works for you! I couldnt reproduce the warning for some reasons


It is indeed fixed.
