Bug#552528: Caused by character set mismatch

Hi,

On my system, alacarte has a segmentation fault if I reconfigure the
locales package to generate the it_IT@euro locale and set LANG to
"it_IT@euro".

While it's parsing the UI definition, it translates "Restore the
default menu layout" to "Ripristina la struttura predefinita del
men�", which uses the ISO/IEC 8859-15 character set. It subsequently
calls g_markup_escape_text on this string, which expects it to use
UTF-8. This causes it to miss the end of the string and, eventually,
to try to access an inaccessible page, causing the segmentation fault.

I don't know where or how this should be fixed.

Python's gettext module provides a bind_textdomain_codeset call, but
adding

gettext.bind_textdomain_codeset(config.GETTEXT_PACKAGE,'UTF-8')

and prefixing GETTEXT_PACKAGE on the previous two lines with "config."
doesn't eliminate the segmentation fault.

Would it be OK to downgrade its severity? If so, to what?
