This error occurs on FOP 1.0 and the latest version from the TRUNK.
The error gets resolved if I remove the text "Page 2", convert the inline to a
block or simply remove the left margin from the simple page master.
After looking into the code it appears that block elements that are inside
inline elements that cause a page break where the next page has a different IPD
is not supported.
The getNextBlockListChangedIPD() function seems to be where it only looks at
for block elements and as a result keeps looking for something it will never
find (since the block is in an inline element).
Thanks
