Vertical text is a new feature of the SVG text engine living in the feature-branch. Vertical text selection hasn't been taken care of yet.
This needs a test case attached (should be easy to make or pull one from the W3C SVG 1.1. spec).
I'm fairly certain this bug no longer exists
(In reply to comment #2) > I'm fairly certain this bug no longer exists > I agree. See http://www.w3.org/Graphics/SVG/Test/20061213/htmlObjectHarness/full-text-align-05-b.html I can copy and paste the vertical text
Seems to be fixed. Please reopen it, if someone finds an example that doesn't work.
