My solution was to poke the bubbles with a nail or needle and
use a siringe of epoxy to fill in the bubble. I got siringes
from a Fleet Farm for livestock. They had larger needles which
is nice since epoxy is somewhat thick.
Back to the current problem, I handled it much the same way as henry except
that I just made a wee slit in the cloth with a sharp utility knife and
squeezed the epoxy in. Aesthetically, it can leave a bit of a mark. If you
are being a perfectionist, you could just spot sand the bubbled cloth off
and do a small patch - carefully done it will be all but invisible.

Then, when you apply your glass, make sure the time is chosen so that room
temperatures are falling. This will help prevent outgassing from taking place
under the glass where it can't escape.
For your current problem, if the areas are small (up to 1/2"), I'd just cut the
glass out, feather the edges, and recoat. The integrity of the envelope should
not be affected much. If they are larger, or you want to be a bit more anal,
cut a piece of glass at least two inches larger all around than the area you
cut out, epoxy it in place, feather its edges after it has hardened completely,
and continue epoxy coats.
When you have all your epoxy coats in place, I'll bet you won't even be able to
see the patch.
