Not sure if it is really a bug (don't know if the the epub 2.0 specification forbids it) but in focus of a better compatibility I hope Ectato will fix it.
This is not a bug but a failure to understand the file system. Unix based file systems are case sensitive always, always. epub and ePub are not the same file so JetBook evidently does not recognize the file as an epub file. Presumably you are expecting the eReader application to automatically start when you click on the file and start the application automatically. It may be that that is under control of a file on the system and the various cases can be added. You could write Ectato and ask for this.
There is nothing in the epub specification that specifies how the file system must work so it is not a specifications issue.
