Hi.

I have a problem with my Clara I can't seem to be able to fix.

Normally I read kepubs, but lately I'm playing with fonts and wanted to open some documents in the epub format, which handles typesetting better than Kobo's engine used to display kepubs. So I sideloaded them to the device without converting to kepub (by disabling "Extended Kobo features" in the Calibre Kobo Touch Extended driver plugin) and I found that my Clara crashes everytime I try to open an epub file.

Same thing happens with plain html files, which seem to be handled also by RMSDK.

Some background: I have a fairly large number of books and my DB is over 700 MB. This probably doesn't matter because I've hidden my books folder with a dot and placed a fresh vanilla database I had backed up and my device still can't open epubs.

I'm running firmware 4.26.16704 and I'm using kobopatch with the following kobopatch.yaml:

## Works with kobopatch v0.15.0 and later.

I'm also running the package with KFMon, KOReader and Plato available here at MobileRead.

Any ideas about what is preventing my device to open epubs? This is driving me nuts. Can I access crash logs anywhere?
