Php – Remote debugging won’t stop at breakpoints

I'm having a problem with xdebug not stopping at breakpoints when using remote debugging (everything is fine when running scripts via the command line). It will break at the first line of the program, then exit, not catching any breakpoints.

It used to work fine, until I switched over to using MacPorts for Apache and PHP. I've tried re-compiling it several times (with several versions), but no dice.

I'm using PHP 5.3.1 and Xdebug 2.1.0-beta3

I've also tried at least 3 different debugging programs (MacGDBp, Netbeans and JetBrains Web IDE).

My php.ini settings look like:

[xdebug]
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_port=9000
xdebug.remote_host=localhost
xdebug.idekey=webide

And when I log the debugger output, setting a breakpoint looks like this/;

<- breakpoint_set -i 895 -t line -f file:///Users/WM_imac/Sites/wm/debug_test.php -n 13 -s enabled
-> <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="breakpoint_set" transaction_id="895" state="enabled" id="890660002"></response>

When run, the debugger will get the context of the first line of the application, then send the detach and stop messages.

However, this line is output when starting the debugger.

<- feature_get -i 885 -n breakpoint_types
-> <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="feature_get" transaction_id="885" feature_name="breakpoint_types" supported="1"><![CDATA[line conditional call return exception]]></response>

Does 'line conditional call return exception' mean anything?
