Bug#479029: Segfault on loading programm icons
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Package: qt4-x11
Severity: grave
Version: 4.4.0~rc1-5
Hello,
I just noticed, that my package fraqtive (uploaded yesterday) segfaults
directly on starting. Here the gdb output:
(gdb) run

The affected lines are:
39 for ( int i = 0; sizes[ i ] > 0; i++ ) {
40 int size = sizes[ i ];
41 QString iconName = baseName + QString::number( size ) + ".png";
42 if ( QFile::exists( iconName ) )
43 m_icon.addFile( iconName, QSize( size, size ) );
44 }
88 QIconEngine* MultiIconEnginePlugin::create( const QString& fileName )
89 {
90 return new MultiIconEngine( fileName );
91 }
I rebuilded all 0.4.x fraqtive releases with the newer qt4-x11 builds
and all versions fail now with the same reason.
While it was working before I think it's an fault in qt4-x11 itself. :(
I'm sorry while I'm at work I haven't got the time to test it with older
qt4-x11 builds and releases.
Another curiosity is, that I just get the following output with
installed libqt4-dbg symbols:
(gdb) run

The trace above is without libqt4-dbg.
