Hi,
we have upgraded to MITK 2015.05.0. The code compiles, but our app
segfaults at start.
Any clue what the problem can be?
The stack trace:

In (2) "clazz" is "org.commontk.service.application.ApplicationHandle",
"filter" is "(!(application.state=STOPPING))"
I guess it is related to the new application launcher mechanism.
Our main function looks like this:
int main(int argc, char** argv)
{
// Create a QApplication instance first
mitk::BaseApplication app(argc, argv);
app.setApplicationName("NiftyView");
app.setOrganizationName("CMIC");
// Preload the org.mitk.gui.qt.common plug-in (and hence also Qmitk) to speed
// up a clean-cache start. This also works around bugs in older gcc
and glibc implementations,
// which have difficulties with multiple dynamic opening and closing
of shared libraries with
// many global static initializers. It also helps if dependent
libraries have weird static
// initialization methods and/or missing de-initialization code.
QStringList preloadLibs;
preloadLibs << "liborg_mitk_gui_qt_common";
app.setPreloadLibraries(preloadLibs);
app.setProperty(mitk::BaseApplication::PROP_APPLICATION,
"uk.ac.ucl.cmic.gui.qt.niftyview");
return app.run();
}
Cheers,
Miklos
