The problem wth ePubs going blank then closing when turning a page could be triggered on my Glo in earlier firmware versions by either of:
* Selecting "Kobo Tsukushi Mincho" from the Aa font menu
* Selecting "Kobo UD Kaguko" from the Aa font menu
In firmware version 4.8.10956 it can now also be triggered by either of:
* Selecting "Publisher default" from the Aa font menu.
* Reading a book where the publisher has forced the use of "serif" or "sans-serif" font families.
For those who are patching the firmware, the two patches to enable to fix the new problems in 4.8.10956 are:
* `Default ePub serif font (Georgia)` (in librmsdk.so.1.0.0.patch)
* `Default ePub sans-serif font (Avenir)` (in librmsdk.so.1.0.0.patch)
(Edit: The `Force user font-family in ePubs` patch might also solve the problem, because it prevents the publisher from selecting any fonts. But using it means embedded fonts won't work, and the whole book will be displayed in just the one font selected from the Aa menu.)
