Interpretation of a column in SQL Server profile trace
The object ID is actually a partition id. This question over on SO provides a simple query to retrieve the needed information.

A side note, since you are using SQL Server 2008 R2 I would highly suggest taking a look into the System Health session that contains the recent deadlocks that have occurred, among other things. Depending on the activity of your instance you may need to pull this information out on a scheduled basis since it is buffer memory so does not stay there long. It is much more efficient to pull this information out than trying to setup a trace and waiting for it to occur again.

I actually wrote up a blog post on this area that includes a script to parse out the information where it is a bit more readable. The blog post is here, the script is below:

    join sys.dm_xe_sessions s on s.address = st.event_session_address
