Hi, i have an other problem with the 0.16 version in an a little bit bigger project. If the code grows at some point it seams that the garbage collector kills my callbacks (made with libglade). Then it gives me the following error message: gladetest.rb:226: warning: GRClosure invoking callback: already destroyed To get it again working it is enough to simply comment out some lines of the code.

Sorry, no solution from my side, cause i don’t know that much about the binding stuff.
