sliding_window_min_ff: fails at runtime: out0 not defined (commit 539f2ba1005d)

  File "/home/acolin/dev/edbsat/kicksat2gs/build/pkg/lib/python2.7/site-packages/kicksat2gs/sliding_window_min_ff.py", line 44, in work                                                         
    out0[k] = amin(in0[k:k+self._length])                                                                          
NameError: global name 'out0' is not defined     

Any tips for what could be the reason? Thank you!

But now it fails with

I've replaced osmocom Source block with File Source with complex output if that matters.

Don't know if this makes any sense, but at least it runs and I can observe an FFT plot:
