EXCEPTION: Error: Expected int32 as second argument

Hello fellow Ioners

I’m trying the tutorial on Ionic 2 on a CentOS 7, with Firefox as browser.
I can’t make it to run on the browser. I get a blank page.
The browser console displays the error:
EXCEPTION: Error: Expected int32 as second argument

Actually I can’t run any of the templates (I tried ‘blank’ and ‘tabs’ and I get the same error).

Everything works fine if I use Genymotion and the android build.

Anyone seen/solved this?

Thank you
Costas

Hmm… Updating my Firefox to the latest stable version (45.0.1) did fix this issue.
It seems to be an error with shim and my Firefox v38 that I had.
