libglib2.0-0t64 vs libglib2.0-0 dependencies

Hi all,
I have noticed that there have been a few broken packages on the
repository for some time, that presumably need to be rebuilt or fixed
after libglib2.0 moved to t64. Notably I have been wanting to install
xpra for a while but it has not been updated.

Is this a problem specific to our port or is it a wider problem? Is it
being tracked anywhere? A brief search didn't turn up anything.

Thanks,
Ed
