It seems that you are trying to dereference a null pointer in magickfontdlgimpl.cpp on line 208.

MagickFontDlgImpl::changePointSize() gets invoked because of this line:

this->cboPoint->setCurrentText(QString::number(this->getpsize()));

this->cboPoint->setCurrentText(QString::number(this->getpsize()));

To copy to clipboard, switch view to plain text mode

I don't quite understand. Why do you think it is this line? The backtrace goes on. It seems to crash somewhere in QRect. Doesn't this look more like a Qt bug?

Look closely:

#1 0x000000000041602c in QWidget::width (this=0x0)
at /usr/lib/qt3/include/qwidget.h:768
#2 0x000000000043d976 in MagickFontDlgImpl::drawMagickFont (this=0x719610,

Some pointer was left uninitialized.

No.

No.

Outch, thanks. The big red font was necessary yesterday.
