Comment 9 for bug 133165

conflicts with earlier library versions are a bad thing. all packages dpending on the old library package have to be upgraded before you can install the new library without removing applications depending on the old library.

config files in library packages are bad as well. local changes are just overwritten by the new package. the correct solution IMO is to put the config file in a package libmtp-common and let the library depend on it. this doesn't solve the problem for the 5->6 upgrade, but for further upgrades.
