Issue

Trying to transfer funds (with or without metamask) on the truffle webpack demo causes an error with ethjs-abi decodeEvent - topics is undefined.

I have narrowed this issue down to something having to do with event indexing - if I remove the indexed parameters from the Transfer event in the MetaCoin contract, this issue does not occur.

Steps to Reproduce

On Windows
Prompt1
truffle.cmd init webpack

Prompt2
testrpc

Prompt1
truffle.cmd compile
truffle.cmd migrate
npm run dev

Go to localhost:8080 and attempt to transfer funds to any address

Expected Behavior

Fund transfer succeeds and website shows success status

Actual Results

Transaction succeeds but console error is thrown on ethjs-abi decodeEvent - I'm not sure if it's an issue on their end or truffle's.

Environment

• Operating System: Windows 10
• Truffle version: 3.3.0
• node version: 6.11.0
• npm version: 5.0.3
