Further info on this bug ...
The crash is on line 133 of ap_UnixTopRuler.cpp
That line is
DELETEP(m_pG);
XAP_UnixApp * app = static_cast<XAP_UnixApp
*>(m_pFrame->getApp());
XAP_UnixFontManager * fontManager = app->getFontManager();
133-> GR_UnixGraphics * pG = new GR_UnixGraphics(m_wTopRuler->window,
fontManager);
m_pG = pG;
UT_ASSERT(m_pG);
This is in the function
void AP_UnixTopRuler::setView(AV_View * pView)
Which is called from line 109 in ap_TopRuler.cpp
void AP_TopRuler::setView(AV_View* pView, UT_uint32 iZoom)
{
109-> this->setView(pView);
UT_ASSERT(m_pG);
m_pG->setZoomPercentage(iZoom);
m_minColumnWidth = m_pG->convertDimension("0.5in");//TODO should
this dimension be hard coded.
}
The debug stack trace is:
(gdb) bt
#0 0x80bab8c in AP_UnixTopRuler::setView (this=0x82fa4b0,

Hope this helps someone. Then again, maybe I'll figure out what's wrong.
