The messages (with booby) are numerous and happen when I
use the color picker of the Sketcher plugin. I also had one freeze and
one crash. Unfortunately the dump is not from root. I tried again as
root but, for now I have not had a crash.
NOTE1: I use a lot of PNG still images, derived from Inkscape's SVG
and exported as png. It seems to me that Cin mishandles this format
and accentuates playback problems in a similar way to the MKV
container.
NOTE2: How I catch and read a Booby?

Thanks for the dumps!  I will have GG reply on "how to catch and read a Booby" after we have a new CinGG checked in.  The current version you are using will most likely show the same booby and GG has generated a fix for that one and for IgorB's issue #135 BUT we have to do more serious checking before releasing it. 

I am not sure we have a fix for the shuttle wheel "wheeling" around yet though.  I can not get the freeze when using the ShuttleXpress and GG is using the ShuttlePRO that seems faster.  gg/Phyllis
