This creates a new array that you are responsible for releasing when
you're finished with it.

This creates a new array that you are *not* responsible for releasing.
Because you assign the result to theContextInfo without releasing the
previous array, that one leaks. Because you expect to use the new
array later, you should have retained it.

The memory management guidelines:
<http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/MemoryMgmt/MemoryMgmt.html>
Additionally, I'd recommend making theContextInfo into an instance
variable, rather than passing it through the contextInfo. You can then
write (or @synthesize) an accessor method that encapsulates all of the
relevant memory management into one place, which is *far* less
error-prone than scattering -retain and -release calls all over the
place.
