CRASH 5.1a Beta 2 (and stable) on Read Aloud NA28

This crash happens to most users who try to Read Aloud the Greek Audio NT text of NA 28 (NA 27 and comparable ressources will work). 

It has reported in detail in this thread: http://community.logos.com/forums/t/73077.aspx - but as I can see, so far without logs being posted. The crash has been observed there for various versions of Windows 7/8 (32bit, 64bit) and Mac OS X

EDIT: the discussion started as a praise for the feature, then centered on the aspect that the feature works great for NA 27 but only for some users with newer NA 28, trying to "force" Read Aloud in NA 28 even though it is not offered in the resource tile menu revealed the crash, starting from Sleimans post: http://community.logos.com/forums/p/73077/510367.aspx#510367  on page 2 /EDIT 

Steps to reproduce:

• One needs the Greek Audio NT (Schwandt) and NA 28
• Open NA 28
• Command "Start Reading Aloud" 
• Either it will work (some users, on desktops) or crash Logos 5 latest beta or stable version
