Can't use Xdebug anymore

Since yesterday phpstorm stopped working with xDebug.

Environment:
- Mac OS X 10.9
- MAMP PRO 2.1.4
- PHP 5.4.10

This, from terminal, shows nothing:

netstat -an | grep 9000

I'm using MAMP PRO, with PGP 5.4:

$ ls -alr /usr/bin/php

lrwxr-xr-x  1 root  wheel  44 15 Nov 15:40 /usr/bin/php -> /Applications/MAMP/bin/php/php5.4.10/bin/php

$ which php

/Applications/MAMP/bin/php/php5.4.10/bin/php

This is the content of .profile (not idea of what created that: I might have done it, but I don't remember when or why):

test -r /sw/bin/init.sh && . /sw/bin/init.sh

export PATH=/Applications/MAMP/bin/php/php5.4.10/bin:/sw/bin:/sw/sbin:/usr/bin:$

There are no .bash_profile or .bash_rc files.

You can find phpinfo and phpStorm PHP setting attached.
Always in the attachments, you can see the remote environment validation (though, before having the issue, I didn't have to configure this, or to validate it).

If I add a breackpoint, enable the debug listener and click on the browser bookmarklet, nothing happen when I open/refresh the page.

If I add to the test script this:
echo 'xdebug_is_enabled() = ' . xdebug_is_enabled();

I get:
xdebug_is_enabled() = 1
