Hi,
Looks like a very promising program but I am having trouble on Linux.
I can load and edit collections file. But the left pane with the list of books does not show any books. I get these errors in the console:

Loading documents..............Traceback (most recent call last):
File "./Kindelabra.py", line 108, in load
self.refresh(widget)
File "./Kindelabra.py", line 391, in refresh

book = Ebook(fullpath)

self.meta = ebook.Mobi(path)

sections = Sectionizer(filename, 'rb')
File "/home/user/Downloads/richardpeng-Kindelabra-ff6185a/ebook.py", line 17, in __init__
raise ValueError('invalid file format')
ValueError: invalid file format


Thanks,
