Bug#621053: libqt4-webkit: All webkit based qt4-applications always crash when they don't find a lot of free memory
Package: libqt4-webkit
Version: 4:4.7.2-3
Severity: normal
Tags: upstream
All applications that use libqt4-webkit crash with segafault (eg. arora,
goldendict, even webkit demos from qt-demo).
Here is a cut from strace log:
