maemomm TextView doesn't allocate default buffer (not wrapped)

[VLG <3rdshift comcast net>]

Murray, Johannes,

I installed both hildon-fmmm-dev and hildon-libsmm-dev in my Scratchbox
1.0.7 SDK_X86 and tried to port an application of mine to nokia 800. 

Thanks for the slick manual[1] and reference[2] and .deb packages of
much reduced size. 

1) One typo I ran into Ch.3 'Installation' from Prebuilt Packages is the
command to install both packages: 

$ fakeroot apt-get install libhildon-libsmm-dev libhildon-fmmm-dev

should rather be

$ fakeroot apt-get install hildon-libsmm-dev hildon-fmmm-dev

2) The other thing so far is the Gtk::TextView - it looks like something
is wrong with the TextView not getting allocated the default TextBuffer.
The attached examples illustrate the problem. If executed in the
scratchbox, they would produce the following results:

[sbox-SDK_X86] > textview-bad

textview-bad[11900]: GLIB WARNING ** glibmm - failed to wrap type of
'GtkTextBuffer'
Segmentation fault (core dumped)


[sbox-SDK_X86] > textview-good

works as expected.

Any chance of fixing this? Both packages are at the version 0.9.1-0

thanks for all the work,
--Vlad
