Bug#601742: cheese: Crashes at startup with SIGSEGV in gst_mini_object_copy

[James Collier]

Package: cheese
Version: 2.30.1-2
Severity: important

Steps to reproduce: start cheese. When it tries to grab (the second?)
frame,
gets a SIGSEGV. The first frame is displayed in cheese when the crash is
caught
under gdb.

GDB output:
