MAC table Seg Fault

[cbl]

Running a WS-8-250-AC on 1.3.3. The Mac table on the web never seems to load, pulling it up on the CLI I get this:

# show mac table
Segmentation fault
MAC Port VLAN Manufacturer Last IP
----------------- ---- ---- ------------ ---------------
json_object_from_file: error reading file ../tmp/mactable.json: No such file or directory

Anybody have any ideas?
