When viewing the Workflow history, you should be able to see the error that triggered the try-catch block on the "Messages" tab. Is that not working in your case?
Some errors will show on the Windows Event Viewer on the server running LFWorkflow - but having a try-catch block is intended to catch the error and handle it, so it probably won't get to those logs.
The Workflow Administration Console keeps error logs too. I checked one of mine that I know always hits the Try-Catch block (it is populating a very large form and thinks it Times Out when it actually succeeds). Not only do I see the error on the "Messages" tab on the Workflow history, but I also see the error on the "activity errors.log" file from the Workflow Administration Console.
