[xdebug-general] call/return type breakpoints against class methods don't work

Hello,

In my local environment the feature of breakpoints with call/return
types against class methods seems not work.

Once Looked in the ML archive I found a thread about this:
http://xdebug.org/archives/xdebug-general/1097.html

So I did same things but it still failed.

I'll attach details below.
Any suggestions would be appreciated.

Thanks in advance.
