Re: libegg (egg-dock) and gtksocket/gtkplug

Hi

The docking stuff was written by Gustavo, so I'm CC-ing him.

This is just a guess, but:

1) Have you tried ref()ing the widgets that are getting destroyed
explicitly ?
2) Are you using the latest code from libegg, which has seen some memory
management and other fixes in the past week or two ?

Rgds,
Biswa.
