Product: Kobo Glo (untested on other devices)
Firmware: 2.8.1
Plugins: Kobo Touch Extended Driver 1.5.0 (not really needed)
File types: KePub
Sideloaded or from Kobobooks: both
On external SD: internal memory only. It has not been tested on external SD.
Steps to reproduce:
- get a kepub with embedded fonts (there are attached two examples created for testing purpose)
- set "document default" font on your device
- open the TOC and tap on a chapter. Not all chapters cause the issue. Those chapters defined in the same xhtml file are very likely to make your device to hang up. However, "testTOC_0.kepub.epub" has 4 chapters defined in 4 different xhtml files and yet it seems not possible to jump to chapter 3.
Current result: Kobo device freezes.
Workaround: setting any fonts exept "document default" one.
Note:in order to recreate the issue with kepub coming directly from kobobooks, here is a an example:

You cannot download it for free though, and it is protected with adobe drm.
In general, almost all ebooks from Garzanti publisher (italian books) are suitable to reproduce said issue.
Update:
When the screen gets blank, endlessly trying to load the page, here is a way to recover. Just tap on the title so that a menu appears at the top of the screen. Then tap in the middle of the page. All characters will get back again. Of course, this does not solve the fact that the chapter loaded might not be the one you had selected.
