iBooks issues with corona and Absinthe

It seems that the latest corona (even the one included in Abstinthe) has some issues with iBooks.
I haven't seen those issues right away since I usually read books without DRM.

I'm searching what's going on...
If you know free books from the store that have issues please comment this post and let me know the title.

PS: I need to buy a MacBook to continue my researches, please support me by clicking Donate. I'm not rich enough to buy one by myself.

Update #3 : Corona 1.0.8 is on Cydia, you have to install it to get the fixes for iBooks.
All devices are OK with this update, EXCEPT iPhones 3GS old bootrom.

Update #2 : @planetbeing pushed a modification on corona git repository that makes an other patch on the kernel for fixing issues on iBooks : stay tuned !

Update #1 : It seems that some PNG have format problems :
