I was trying to copy the data from one list (MOSS 2007 site collection) to another existing list in (Sharepoint 2010 site collection)but getting an error : "create pending type Absences in list library Absences.Cannot complete this action please try again. 0X80004005". Please help to resolve this issue.
Please check SharePoint ULS logs for more informative error message.
You can create the required content type in the target list manually... as it's seems to be related to Fab40 which may have some specific configuration...
These can be the causes of error 0x80004005
