Crash in Qt3

I'm working on a private branch of kyzis (http://www.yzis.org) and I've come
across a strange crash in Qt.  The backtrace only contains Qt code and is
100% reproducible The crash occurs with both debian's Qt 3.3 and KDE's
qt-copy.  It always happens when trying to allocate 513 bytes for a
QCString.  I was wondering if anybody could give me some hints for
debugging this one.  I can post my yzis snapshot somewhere if that helps. 
I've been bashing my head against it for a couple days now.  Thanks.
