[PD] Latest gem troubles - pix_multiimage and pix_imageInPlace crashing

[James Dunn]

After getting text3d working, I've now run into some problems with 
pix_multiimage and pix_imageInplace causing pd to crash. This happens in 
my patch, but also if I open 
doc/5.reference/Gem/pix_imageInPlace-help.pd or pix_multiimage and click 
the open/preload message. Running pd from a terminal I get:

running from gdb I get:
