I can confirm this bug with LibO 3.4 rc2 on Linux.
Same bug in OOo. It is there in DEV300m88 and not there in DEV300m90.
I sent a patch to the mailing list fro review.
Andras: Thank you for the fix, I pushed it to libreoffice-3-4.
RC2 is bit by bit identical with release version, so separate items in the version picker are useless. Changes have been discussed with Michael Meeks.
