In fact it looks like a bug because it ended up concatenating 'file://' somewhere in the middle of the path which makes no sense.

From the +fileURLWithPath:isDirectory: documentation:
"If path begins with a tilde, it must first be expanded with stringByExpandingTildeInPath."

Note also that paths with '~' in them are treated differently in sandboxed apps.

Don't do that. +URLWithString: expects a string that represents a URL, not a string that represents a filesystem path.
