Hmm, a serialization issue is unlikely, since all the other plug-ins seem
to work, and script-fu never could be called reliably. If this, however,
is indeed the case than this change is probably quite new (maybe somebody
hacked locking lately?)

Just pass it in at the usual position.

Did you pass in a valid image, or did you try to pass in a number? The latter
might not work reliably. You can also try to use the all-explicit syntax,

No, you pass them "as usual".

you could check this hypothesis by doing something like this:

for (0..29) {
   print "IMAGE ID: ", ${$drawable->image}, "\n";
   select undef, undef, undef, 0.1;

this (untested) snippet prints out the image id of your drawable ten times
a second. Just insert it after the call to drop_shadow (i.e. where you
formerly added the delay).

When the image id changes from -1 to something else we have found the
