With the latest nightly (5.0.1 (6533.17.8, r64727)), clicking on gmail messages does not open them. Further, I cannot open them with keyboard shortcuts (using the 'o') key. Safari 5.0.1 stable works correctly.
I also get this problem, and with different gmail accounts. I am using latest nightly Version 5.0 (6533.16, r64727), and I haven't upgraded to Safari 5.0.1 yet. Using Safari Version 5.0 (6533.16), works as expected.
This should be fixed now. *** This bug has been marked as a duplicate of bug 43557 ***
