I have attached a small C++ program that exhibits the issue. I have also attached a backtrace/memory map that was produced by running the program. This program executes and exits cleanly on openSUSE 12.1. I installed 12.1 in a VirtualBox VM and updated to KDE 4.8 and QT 4.8 via the KDE update repo. In that environment the waitForStarted doesn't return until it timesout (Default 30 sec). On openSUSE 12.2 Factory it segfaults. I am using the factory-tested repos and I have applied all updates. Since it doesn't crash in 12.1 with Qt 4.8 it is unlikely to be a QT 4.8 bug. This bug was discovered in the OpenLP program in devel:languages:python, which I maintain. OpenLP is a Python program but I have been able to reproduce the issue in C++ which eliminates Python and python-qt4 as suspects. In OpenLP this bug occurs when using the Presentations plugin which uses QProcess.startDetatched() and QProcess.waitForStarted() to start LibreOffice Impress.
