The documentation warns that
http://www.harrisgeospatial.com/docs/IDL_IDLBridge.html

"Debugging a routine running in a child IDL process presents challenges not present when debugging routines running in the main IDL process. Child IDL processes have no direct connection to the parent IDL process."

I agree that the documentation is ambiguous about whether one should be able to use ON_IOError in the child process. Two things I would try:

1. Use the FILE_TEST() function to test for a valid file.
2. Have an error parameter which can be passed between the child process and the main process
