Error Unable to fetch authentication_scheme in application 134.

Question

Hi,
I got the following error while migrating one of my application from one workspace to another in the same APEX (2.2) instance but the schemas are different in both cases.
"Error Unable to fetch authentication_scheme in application 134."
Here are the more detailed information:
1) I have a workspace 'SUM_DEMO' under schema 'DEM_DEV'
2) Created a new workspace 'MUD_DEV'. Also, created a new schema 'MUD_DEV' in the process of creating this workspace. I had choosen 'New Schema' rather than 'use existing schema' and created this new schema.
3) Developed an application 'TestPrinter' in workspace 'SUM_DEMO'.
4) Export this application using Export functionality of Apex.
below are the some of the parameters that I have selected during export.
     Owner Override : MUD_DEV
     File Format: DOS
5) Import this application in workspace 'MUD_DEV' that is under different schema 'DEM_DEV'.
below are the some of the parameters that I have selected during import.
     Parse as Schema: MUD_DEV
     Auto Assign New Application ID
6) getting this error:
     "Error Unable to fetch authentication_scheme in application 134."
though application 'TestPrinter' doesn't has any authentication !!
For more information, I am pasting the debug information from the page.

Please suggest me some way to get rid of it.

Sumit,
5) Import this application in workspace 'MUD_DEV' that is under different schema 'DEM_DEV'.I don't understand "under different schema 'DEM_DEV' ". How many schemas are assigned to workspace MUD_DEV and what are those schema names?
What do you want the parsing schema of the application to be in the MUD_DEV workspace?
