Ouch! I only got 1 thin crack ... but I had no idea where it came from. Now I guess it must have been from the staining. I wanted to make sure that the crack didn't spread further so I just used some thin CA glue. I had to scrape it all the way back because the glue kept the re-stain from taking. That seemed to work for me. But I cannot say whether CA glue is the way to go for your case.
