#4 Libe-book dont work with some files

[Bruno Baruffaldi]

Hello, I am trying to add libe-book to Xapian but it seems that there are some problems with some formats.
Libe-book works well with the corpus that I find inside the project, but it seems to fail with the attached files. Is it possible that the files has something wrong?

One of them(ClosestPair) don't pass the confidence checking and the other(Cuda_course) during parsing (dont return EBOOKDocument::RESULT_OK).

Here is the code of my code.

Re ClosestPair.pdb: it's not a supported format. Type/creator is vIMG/View; file(1) identifies it as "FireViewer/ImageViewer PalmOS document".

Re Cuda course.fb2: one of the images is apparently damaged so decoding from base64 throws an exception. That should be handled and the image skipped.
