Use gdk_threads_enter/gdk_threads_leave to ensure gtk multithread safe

If the video player tries to play an unknown type file, it will enter
the error_cb() function, which is called in another thread.
Use gdk_threads_enter/gdk_threads_leave to ensure the safe of gtk
multi-thread operation.

This fixes [BUGID #474]
