Thank both of you guys very much for such a fast answer!
Pleasantries first, thank you user_none for your kind remarks and helpful advice. As you may have noticed, I'm using blank lines to separate paragraphs now
I tried to make my message as explanatory as I could, glad to hear it didn't bother you.
And now for the really icky part. Following Kovid's advice I downloaded Calibre 0.6.28 (the 686 tarball, which corresponds with my system architecture). When I run it, either with or without sudo, the program starts, but it displays an error window saying "ERROR: ERROR: Unhandled exception" in it's title and "KeyError:'ondevice'" in the window itself. Quite a nasty one, I must say, as no matter how many times I close the error window, it just pops open again. The only way I found to actually stop and close the program is to kill -9 it.
Here's the console output:

So... Any thoughts? I know my way around Linux and OS's in general, and besides that I'm a junior programmer, so make it techie if you have to. I'm just intrigued to find out what's wrong and to fix it with your help so I can finally enjoy Calibre on my Ubuntu
