** Description changed: The ubuntu-ui-toolkit test segfaults (bug #1266707 etc) may be because V4 engine seems to crash if /proc is not mounted. I noticed this when building in a chroot environment with and without /proc mounted. Just executing './tst_components -platform minimal' in ubuntu-ui- toolkit/tests/unit/tst_components crashes as follows: #0 __GI___libc_free (mem=0x18) at malloc.c:2888 #1 0x00007ffff4ed3cfd in __pthread_attr_destroy (attr=<optimized out>) at pthread_attr_destroy.c:41 #2 0x00007ffff579ed86 in QV4::MemoryManager::MemoryManager() () from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 #3 0x00007ffff57843bc in QV4::ExecutionEngine::ExecutionEngine(QQmlJS::EvalISelFactory*) () - from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 + from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 #4 0x00007ffff59021f2 in QV8Engine::QV8Engine(QJSEngine*) () from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 #5 0x00007ffff577f294 in QJSEngine::QJSEngine(QJSEnginePrivate&, QObject*) () from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 #6 0x00007ffff5834170 in QQmlEngine::QQmlEngine(QObject*) () from /usr/lib/x86_64-linux-gnu/libQt5Qml.so.5 #7 0x00007ffff5e95298 in ??
