I thought I had a reliable layout test. Nope. Doesn't crash all the time.

Coming up with an automated test that only requires ATK (rather than AT-SPI along with an AT) is proving challenging. Came up with a different test case for the same problem. Will try it and unit-style. But I am reaching the point where I will accept pity too. ;) It's a sanity check which solves a crasher and it could be fixed if only I could come up with a magical test. :-/
