Will it still decode with this "memory leak"?  

I need a baseband P25 sample file to test and get familiar with the scopes. I am unsure of my ezcap tv tuner and i am unsure of capturing a signal with the discriminator tap (i dont even know what kind of file i should save it as!). I really need a sample that is known to be good so that i can learn what it looks like on the scopes. 

for the record id like to say that setting .gnuradio/config.conf to: 
 
[wxgui] 
style=gl 
 
(instead of 'style=nongl') has killed the 'set callback' and 'swig_pmt.i' attribute errors.  Balint brought the opengl issue to my attention.  the 'fsk4_slicer_fb' attribute error was fixed by reinstalling op25; apparently somehow i had a very old version of op25 that didnt have the slicer.  Max exposed this weirdness by looking at:

>>> from gnuradio import op25
>>> dir(op25)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '_newclass', '_object', '_op25', '_swig_getattr', '_swig_property', '_swig_repr', '_swig_setattr', '_swig_setattr_nondynamic', '_swig_setattr_nondynamic_method', 'decoder_ff', 'op25_decoder_ff_sptr', 'op25_decoder_ff_sptr_swigregister']
>>> 
 
Thanks everybody!  
Matt

please if anyone has a good sample of baseband P25 please share a file or two with me.
