[PD] Someone sent a bogus pointer to copy2image

[Matteo Sisti Sette]

Hi,

I'm getting this error message very often:

"error: GEM: Someone sent a bogus pointer to copy2Image"
and
"error: GEM: Someone sent a bogus pointer to copy2ImageStruct"

It has started to appear with a rather complex patch which didn't use to 
trigger this error, so i don't know where to start from in order to 
track the issue down (by the way the patch works perfecly).

Does anybody know what the message exactly means or if it is specific to 
some particular object?

I'm using Pd Extended 0.42.5 with gem 0.92.3 on Ubuntu.

Thanks
m.
