AFAIUI there is a symbol collision: Both, the shared library
libglib-2.0.so.0 from libglib2.0-0_2.20.0-1_amd64.deb and the shared
library libgdk-x11-2.0.so.0 from libgtk2.0-0_2.14.7-4+b1_amd64.deb,
export the dynamic symbol g_dgettext. As g_dgettext() is a documented
function of the GLib I would consider it a bug of libgtk2.0-0 version
2.14.7-4+b1 (at least on amd64) to export this symbol too:

$ nm -D /usr/lib/libglib-2.0.so.0 | grep g_dgettext
0000000000059590 T g_dgettext

$ nm -D /usr/lib/libgdk-x11-2.0.so.0 | grep g_dgettext
                 U g_dgettext

If others agree with my analysis this bug should probably get reassigned
to package libgtk2.0-0. Probably this package has build errors (possibly
not linked against GLib?) leading to an undefined (U) g_dgettext symbol
-- but I have to admit that I don't really understand what's going on
here, so I'm just guessing around...
