Comment 1 for bug 357653

For me this seems to work:

-------------------------------
@@ -605,6 +605,8 @@
     # make a list of all ibdata files in the backup directory and all
     # directories in the backup directory under which there are ibdata files
     foreach my $a (split(/;/, $orig_innodb_data_file_path)) {
+
+ $a =~ s/^$orig_datadir//;
         my $path = (split(/:/,$a))[0];
         my $filename = (split(/\/+/, $path))[0];

-------------------------------
But i don't know, if this is a proper fix or if it breaks other setups.
