pldebugger blank code issue

Hello dear list,

I'm having trouble after setting up pldebugger git-current
(eb754b6ba9a1c18e7bc4ddf521408be06768c697) commit in a Ubuntu 10.04.01
x86_64 box. Server versión is 9.1.5.
The issue is that once I start debugging a PLPgSQL function within pgAdmin,
once it goes one level down the call stack, the given function's code isn't
shown despite being a proper plpgsql function. You can run it step by step
or continue, and execution is correct (even DBMS messages are displayed in
the bottom pane), but I just can't see the code displayed in the main pane.
If I manually click the original (main) function in the right pane, his
code is shown properly. It seems that certain functions are forbidden from
being shown in the main pane.
I tested this setup with pgAdmin 1.14.0, 1.14.3 and 1.16.0-beta4.
Any idea anyone?

On the side, I see a lot of people having problems these days with 9.1.x
releases. Is current code production-ready?

Thanks in advance,
