Hi,

I'm getting segmentation faults when running the following unit test. When I comment either one of the two lines in testLogin, the program runs. So it only happens when the job is actually executed, I think.

Any ideas?

void GDataClientTest::testLogin()
{
    KIO::TransferJob *job = KIO::get(KUrl("http://www.kde.org"));
    QTest::qWait(1000);
}

QTEST_MAIN(GDataClientTest)
#include "gdataclienttest.moc"

You need a valid KApplication instance in order to use most KDE library functions, since translation is required.

Using QTEST_KDEMAIN_CORE(GDataClientTest) instead of QTEST_MAIN(GDataClientTest) fixed it indeed.

Thanks!
