The bug that sees apps crash immediately after they are downloaded or updated sucks, no question. But Apple has apparently told developers that it's aware of the issue and is currently working on the issue.
In a statement reported by TechCrunch, Apple said:
We are aware of the issue related to apps crashing after update. We are currently working on resolving the issue. Stay tuned for updates.
Shouldn't be too long now. [TechCrunch]
