Hi everybody!

I've recently taken to install Calibre on my headless Ubuntu LTS 14.04 in order to experiment with mobile content delivery. More mundanely (and quite probably more honestly ) phrased: I am too darned lazy to load 50 books on my Oppo Find 7 running Mantano Premium and I want to be able to download my locally-stored books on the go (when commuting to work or while on vacation). It's partly a storage problem, but then I would've been better off just forking over the cash for a larger microSD card.

So far it is working brilliantly! Mantano accepts my server as a content server, I can download the files, they get imported, I can read them -- there's always a 'but' --- but Calibre acts up when editing from my Windows 8.1 x64 box.

I just keep running into various smaller messages that seem to signify there are minor issues. For example (since last update):

==> Vlaag van verstand
Traceback (most recent call last):

CorruptError: CorruptError: database disk image is malformed

Why is referring to Kovid's C: partition?

Or:

calibre, version 2.20.0

CorruptError: CorruptError: database disk image is malformed

Sometimes I can re-edit and it works, sometimes a title change sticks anyway, and seems to ignore the error message altogether. Sometimes, even a restarted Calibre just throws the same error again first edit in.

Would you think this is a permissions issue (everything is 777'd locally), or is it something to do on the compilation side? Am I missing something?
