Errors in starting channels

[fennerm]

I get a series of errors on startup from ncm. Full log files are attached but the basic error is just this repeated a bunch of times:

Error detected while processing function <SNR>28_on_core_channel_error: line 1: INFO:cm:source <cm-tmux> channel pid: 23530^@ Error detected while processing function <SNR>28_on_core_channel_error: line 1: DEBUG:cm:core method cm_start_channels completed^@ Error detected while processing function <SNR>28_on_core_channel_error: line 1: INFO:cm:start_channel for cm_sources.cm_bufkeyword^@ Error detected while processing function <SNR>28_on_core_channel_error:

I still get the errors even if I remove everything from my init.vim except ncm.
