Seifeddine Dridi commented on FOP-2292:
---------------------------------------
The cause of this bug is still unknown to me. But after a couple of tests, the
NullPointerException seems to be also related to having different margins
across pages, which triggers an IPD-change. Setting the left/right margins
equally in all fo:simple-page-master fixes the error...Any suggestions?
