+rTorrent sometimes creates invalid torrents which has empty path components.
+the bitorrent spec allows for "" strings, but they make no sense in paths.
+so instead of always adding a / in between, skip them.  ugh.
+
+for example:
+dict {
+	'info' => dict {
+		'name' => str = "some dir" (len = 8)
+		'files' => list [
+			dict {
+				'length' => int = 12345567
+				'path' => list [
+					str = "" (len = 0)
+					str = "foo.bin" (len = 7)
+				]
+			}
+			...
+		]
+		...
+	}
+	...
+}
+
+ctorrent will then try to fetch the file "/some dir/foo.bin" instead of
+"some dir/foo.bin" (relative to $PWD).
