It's definately fixable without reformatting.
When I designed the on-disk ACL/xattr format, I built in a magic number and a checksum to catch things like corrupted entries wreaking havoc on the system. That's what you're hitting.
Somehow, an entry wasn't fully written to disk or was corrupted somehow. ~ Whether it was part of the extending process or not, I couldn't tell you.
You can use debugreiserfs to track down the file with that key by using debugreiserfs -d <device> and looking for the objectid. Once you find the directory listing with that key, you should be able to find the file.
When you've located the filename, a setfattr -x system.posix_acl_access <file> followed by the appropriate setfacl command will reset the ACL.
