What's the error you get? this depends on lang-python, do you have it installed?

[s0i37]

Yes.
r2pm -ci rlang-python
r2 -I windbg.py -D windbg windbg://target
_check windbg://target False
_open windbg://target 5 420
[1] 980827 segmentation fault r2 -I windbg.py -D windbg windbg://target

[trufae]

can you paste the backtrace?
