I can't reproduce it on a Pixel emulator with Android 4.1. Can you share details about the device/emulator you had the crash on?

Hi guys, is it possible for this to be back-ported / merged on 7.5.X? Thanks!

[~ygbr], no. It won't be back-ported. The TabGroup code has been completely re-written and is a bit of breaking-change since it no longer depends on the ActionBar. On the plus side, you can now globally use a "NoTitleBar" theme since the ActionBar is no longer required. On the minus side, the tab bar is no longer embedded within the ActionBar when landscape and always appears below it, eating up vertical space. Breaking-changes like this belong in major revisions of Titanium for app developer to opt-in to.
