Symptoms
When using the K2 pages Display Form it doesn't load - Guid error (Guid should contain 32 digits with 4 dashes), OOTB SP display form works fine.
Diagnoses
The Url contains the actual SP list id and the list ID is URL encoded and thus not in GUID format.
Resolution
Patch was provided. This will be fixed in Appit 1.5 Update 3
