Comment 3 for bug 414594

> what i was trying to get at was: installations of exaile may break if a prefix is used that is not in the list of xdg defaults.

Yes, but the default prefix _is_ in the set of paths, and therefore it is my opinion that it is the user's job to ensure that they set XDG_DATA_DIRS appropriately if they choose a non-standard prefix.

> at the very least, the installation instructions should include a warning about the possible consequences of doing that.

true, this is worth mentioning.
