dupe of this? http://bugs.kde.org/show_bug.cgi?id=143281 Could well be. Except from me running this with a nonstripped binary and gettin linenumbers. Did some more investigation and the problem seems to be the RenderBlock::parent() returning something strange. Yep,
parent() returns 0 in my case, maening that the line:
if(parent()->canClear(this, (m_avoidPageBreak) ? PageBreakHarder : PageBreakNormal )) {
breaks.
I patched by testing for a zero condition, but as I don't understand exactly what is going on here it would be nice if the original creator took a look at it. There is also one more place with the same test. Does it need the same patch?

Patch for null pointer/object
will return to this bug; need access to a printer. As stated in bug 143281: "Closing this bug as WORKSFORME as we won't fix KDE 3.5 anymore." I'm marking this as a duplicate of that bug. *** This bug has been marked as a duplicate of bug 143281 *** |
