when i try r2diaphora /bin/ls

Has there been a change in r2pipe, while the corresponding part in the project has not been updated yet?

The trace indicates that the exception is being produced when executing the command e log.level=0 (the first r2 command executed in r2diaphora) because it can not find the symbol _r_core_cmd_str in RCore. I doubt this has anything to do with r2diaphora and as such I can not do much from my end. My guess is that the bug is either in the radare's core .so or in r2pipe.
