Jeremy Katz asked on fedora-trans-list to look through the screenshots available at http://people.redhat.com/~katzj/anaconda-langs/ and file bugs. So, on the screenshot attached you can see Disk Druid screen with the raw of buttons: Create, Edit, Delete, Cancel, RAID, LVM. First, the fourth button's text (highlighted by red) is longer than the button so it doesn't fit in. Second, the aligment of text on all buttons is, well, strange - it is different on each button, and it's something other than left, right or center.

The alignment is centered, but the buttons try to be equal width which is what makes it strange. As for the button, adding a newline in there would make things fit better (and then the text would center properly and things should fall out okay). Cc'ing the last few translaters in the hope one of them will make the change although I can if I get confirmation that it isn't incorrect to do so.
Fixed in translate cvs.
