[Orgmode] Vertical lines are broken in 6.28?

[Yury GEORGIEVSKIY]

Hello,

I've regenerate my .org doc with 6.28trans (was with 6.24)
and Vertical Lines, I want to keep -- not working anymore.
Ex:

| Legasy machines | # of BC | # of RTI connected |
|-----------------+---------+--------------------|
| /               |       < |                  < |
| pca/ellse1      |       1 |               none |


This was OK before.


Thanks in advance,
Yury
