Description
qtdeclarative/tests/auto/quick/qquickpixmapcache/tst_qquickpixmapcache fails randomly because of an assertion failure in QHttpNetworkConnectionChannel::handleUnexpectedEOF(). I can randomly reproduce the failure by putting some remarkable stress on the system while running the auto test.
Test output and backtrace:
