This linux distribution by default does not include the gstreamer plugin xvimagesink. Therefore, when loading gstreamer in wxwindows it detects this problem and sets "m_imp" to NULL, see wxWidgets/src/common/mediactrlcmn.cpp:143. Then in wxMediaCtrl2.cpp:45 m_imp is NULL and therefore it segfaults in line 46. Should there be a check for this condition?
