The "fork" issue that occurred to Bitcoin is in the Litecoin code, but it only affects people who are mining.  The users are fine (as I understand that issue).  Blocks mined with a certain setting are dis-regarded by the bulk of clients as they do not have that setting.  Any fork (if someone went out of their way to do it), would be short-lived and not effect transactions being processed on the main fork.  It appears there are plans to patch in future lease.  Read on other thread at https://bitcointalk.org/index.php?topic=47417.msg1726129#msg1726129
