Converjon fails on Node v6 w/ "options.hasOwnProperty is not a function"

[graste]

After installing a newer nodejs version converjon stopped working. Error is options.hasOwnProperty is not a function. Excerpt form the debug/error log:

[DEBUG] 2 Target file doesn't exist. Must be regenerated.
[DEBUG] 2 Applying cropping and constriants
[DEBUG] 2 Released lock: metadata
[DEBUG] 2 Released lock: source file
[DEBUG] 2 Released lock: target file
[ERROR] options.hasOwnProperty is not a function

When it works the debug log looks more like this:

[DEBUG] 0 Target file doesn't exist. Must be regenerated.
[DEBUG] 0 Applying cropping and constriants
[DEBUG] 0 Requesting image conversion
[DEBUG] 0 Image conversion successful
[DEBUG] 0 Released lock: metadata
[DEBUG] 0 Released lock: source file
[DEBUG] 0 Releasing lock: target file

I checked different node/npm versions w/ converjon 2.7.2:

• node v6.2.1 w/ npm 3.9.3: fails (--no-shrinkwrap fails as well)
• node v5.9.1 w/ npm 3.7.3: works
• node v4.4.5 w/ npm: 2.15.5: works

The tests are running without errors on the node v6 version. I did not investigate further, but think hasOwnProperty and other functions have been deprecated in V8 and have since been removed in version 6.

What's your take at this @lnwdr?

Node 6 has issues with a lot of JS libs and tools at the moment.

For now, i'd say: stick with the 4.x.x LTS version of node since it's the recommended one anyway.
