 While investigating why ThemeChooses doesn't download the selected theme,
 I noticed that the frontend crashed when I run it from the commandline
 with the "-v help" argument.
 It looks like the cleanup tries to destory the GUI, which isn't created
 when querying the debug level / channel information.

 $ gdb -q --args mythfrontend -v help
 Program received signal SIGSEGV, Segmentation fault.

 Since the output is otherwise fine, this is only a minor inconvinience.
 This happens on Debian sid amd64 self-compiled with v0.25-9-gefada3f and
 still with v0.25-86-g50e9b0f
