Node-red crashes

Hello,

I just created a bad flow in my node red-project. Now the node-red refuses to start with the following message:

29 Mar 20:03:38 - [info] Started flows
29 Mar 20:03:42 - [red] Uncaught Exception:
29 Mar 20:03:42 - TypeError: "list" argument must be an Array of Buffers
at Function.Buffer.concat (buffer.js:314:13)
at completeSend (/usr/lib/node_modules/node-red/nodes/core/logic/17-split.js:469:40)
at Timeout. (/usr/lib/node_modules/node-red/nodes/core/logic/17-split.js:630:29)
at ontimeout (timers.js:386:11)
at tryOnTimeout (timers.js:250:5)
at Timer.listOnTimeout (timers.js:214:5)

Any good idea on how to fix this issue?
