Which, as far as I can tell, means: - if possible, get a list of packages in squeeze that expose an affected struct (gstreamer, glibmm, others?) - once we have that, add appropriate Breaks on affected reverse dependencies in e.g. libgstreamer0.10-0 (and others, if step 1 found any), and make sure its shlibs/symbols ensure that newly rebuilt reverse deps get a dependency on a libgstreamer using the new glib ABI - only then rebuild whatever gstreamer plugins (and possibly other packages) are affected. Does that sound ok? Cheers, Julien
