Package: kword
Version: 0.1 (KDE 1.90 Beta >= 20000517)
Severity: grave

Problem description
-------------------

- start kword with an empty document
- mode "Edit Frames" (second icon on the "tools_toolbar")
- now double-click somewhere outside all frames --> SEGV.


Relevant code from koffice/kword/kword_page.cc:

void KWPage::vmdEditFrame( int mx, int my )
{
    int frameset = doc->getFrameSet( mx, my );
    if ( doc->getFrameSet( frameset )->getFrameType() == FT_PART ) {
        KWPartFrameSet *fs = dynamic_cast<KWPartFrameSet*>( doc->getFrameSet( fr

This function is called by void KWPage::viewportMouseDoubleClickEvent
(QMouseEvent*).  If the call to doc->getFrameSet(mx,my) returns -1 (as can be
seen on the debug messages to stdout), the next call to
doc->getFrameSet(frameset) returns NULL...

Fix: check return value of getFrameset(int,int), and maybe others.

Patch - tested and works (on my system at least :-)
Linux/i386 2.3.99-pre8
glibc-2.1
XFree86 3.3.6
gcc 2.95.2

Apply in kde src dir with "patch -p0".

HTH,
Wolfgang Oertl
