It seems Screen Capture Chrome extension causes imo.im to not load. This is repeatable by toggling the extension and refreshing imo.im while logged in. There are actually two issues here that I noticed:
Uncaught TypeError: Cannot read property 'length' of null
- this appears to be related to the extension, happens inside the imo angular module, so I'm not entirely sure. It's the last line here:
if (Os.which === Os.MAC) {
_ref = document.styleSheets;
_results = [];
