Package: libqt4-dev Version: 4.1.1-1 Severity: normal X-Debbugs-Cc: [EMAIL PROTECTED]
Since the update to QT 4.1.1 my application (packagesearch) crashes when calling qApp->processEvents() in some places, everything worked fine with QT 4.1.0. I was not able to reproduce the crash in a small example, but you can pull packagesearch from SourceForge subversion: https://svn.sourceforge.net/svnroot/packagesearch/trunk/packagesearch There are some lines commented out calling qApp->processEvents() (e.g. in src/pluginmanager.cpp). If you uncomment the first qApp->processEvents() call in pluginmanager packagesearch will crash on startup, uncommenting the second works fine though. The error message look kinda weird...: Program received signal SIGSEGV, Segmentation fault.
