[Hydrogen-devel] crash on startup with 0.8.1

[Chris C. <ca...@al...>]

The list archives on sf.net don't seem all that up-to-date to me, so 
this has probably been reported and fixed several times over.  
Anyhow, on SuSE 9.0:

#0  0x40938d35 in XftDrawGlyphs () from /usr/X11R6/lib/libXft.so.2
#1  0x4038e94f in QFontEngineXft::draw(QPainter*, int, int, 
QTextEngine const*, QScriptItem const*, int) () from /usr/lib/qt3/
lib/libqt-mt.so.3
#2  0x4037db59 in QPainter::drawTextItem(int, int, QTextItem const&, 
int) ()
   from /usr/lib/qt3/lib/libqt-mt.so.3
#3  0x4037d875 in QPainter::drawText(int, int, QString const&, int, 
int, QPainter::TextDirection) () from /usr/lib/qt3/lib/libqt-mt.so.3
#4  0x4037d4c8 in QPainter::drawText(int, int, QString const&, int, 
QPainter::TextDirection) () from /usr/lib/qt3/lib/libqt-mt.so.3
#5  0x0808266b in InstrumentNameWidget::paintEvent(QPaintEvent*) (
    this=0x843e700, ev=0xbfffe670) at MixerLine.cpp:1045

etc.

If I comment out MixerLine.cpp:1045, all is well.  Maybe the drawText 
call is attempting to draw outside the extents of the pixmap (e.g. if 
the font matched on this platform is larger than expected -- could be 
worth testing the font extents -- let me know if you'd like me to 
investigate further).

Lovely program otherwise though.
