Re: patch for bug 83532 (partial)

[Marco Colombo <m colombo ed ac uk>]

yo!!!
first of all: thanks richard for the pointer about bug 133772. the description 
of the hang I was talking about in the other thread really looks like the one 
there, I'm attaching my backtrace if it can be of any help.
I've figured that the problem happens because of the "npieces" change in my 
patch. without those, I cannot see any problems with resizing. I'll try to 
narrow it down further.

I'm not using PNG themes, I can see this with both SVG themes (balls and 
shapes). I wouldn't like to pollute bug 83532 with this, maybe should I post 
it to 133772? or create a new bug?
ciao, marco
