I thought I'd take a look and compare the contents and much to my surprise.. as soon as I tried to access the epub I was greeted with an "Oops! This document couldn't be opened... This document is protected by Adobe Digital Rights Management (DRM) and is not currently authorized.. bla bla bla..." popup on the Kobo Glo..!
Now, this rather came as a surprise since I do not "own" any DRM'd stuff, books or otherwise..!
Well, I fired up Calibre and checked my original download.. Sure enough, I got this epub from Project Gutenberg...! So, I tried to open it with Calibre's built-in viewer and it did take an unusual 30 seconds or so to open, but I was able to access it.
The only potential problem with this epub is that it is quite large -- Mr Hume's history adds up to c. 4,000 pages and there are a number of jpeg's as well. All in all the epub weighs in at a whopping 17.3 MB..
I was able to unzip the epub and browse its contents, so I very much doubt DRM is the issue here..!
Is this a bug with the Kobo viewer software failing to open the epub (not enough RAM, perhaps) and misdiagnosing the cause of the failure..?
Has anybody else run into this problem and possibly found a fix or workaround..?
Oh, in case that matters to anybody, the Kobo's software version is 2.6.1 and was last updated 3 months ago.
Thanks,

It is a Kobo problem with some very big files. I had a similar one with a detailed catalogue of my whole library (27.5 MB), which neither Glo nor Aura HD accepted, saying I wasn't allowed DRMs (though I am), but which worked fine on the Sony PRS-T2.
So I limited the detailed catalogue to only those books on the Aura HD (some 13MB), which the Kobos accept.
FYI, I navigated on the Aura without problem in a 20.1 MB dictionary, and I read a 21.4 MB picture book. So it is not only a problem of size, though it does seem to concern only very big files. I have the latest versions of everything, but I first had the problem some time ago, with I don't remember which versions.
[EDIT] I forgot to mention I thought at first it was a Calibre bug, so submitted one. David Goyal wrote that it was a Kobo problem and I should submit it to them. Considering the very poor automated answers I had with deficient bought books, I gave up.
