[Mediawiki-api] Problem with mwclient and EditPage::attemptSave hook

Hi,

I 've setup mediawiki-1.15.1 with the following hook in LocalSettings.php:

$wgHooks['EditPage::attemptSave'][] = 'foo';

Foo is a simple function:

function foo($editpage) { return true; }

With this setup I 've noticed that I cannot save any page with mwclient (ver 0.6.4). The call: page.save(newText)

raises the following exception: File "/lib/python2.6/json/decoder.py", line 338, in raw_decode raise ValueError("No JSON object could be decoded") ValueError: No JSON object could be decoded

When I comment out the hook then the save command works properly. Any suggestions?

My system is a OSX 10.6.3

Thank you Alex.
