Glo Kobo Glo gets stuck when using the TOC to jump to a certain chapter.

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:

1. get a kepub with embedded fonts (there are attached two examples created for testing purpose)
2. set "document default" font on your device
3. 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:http://www.kobobooks.it/ebook/Favole...EnZWdMA5Ww&r=1
You cannot download it for free though, and it is protected with adobe drm.:chinscratch:

In general, almost all ebooks from Garzanti publisher (italian books) are suitable to reproduce said issue.
