I don't think this bug has anything to do with f*ed-ness state of libzvt.
I think it's something relatively simple having to do with libzvt 
not properly handling the background pixmap being destroyed.

The f*ed-ness state of libzvt is essentially:

 * Nobody (except maybe Zucchi) understands the update code.
   Some parts of the update code (the scrolling in particular)
   probably need significant rewriting.

 * Nobody is prepared to make decisions about terminal emulation
   bugs reported against libzvt, and the terminal emulation code
   is structured in a fairly chaotic manner.

 * The code is making assumptions about the relationship between
   bytes (or in utf-8 mode characters) in the input stream and 
   cells in the output fixing it for i18n really, really difficult.

I don't think we need to live in denial though; we should be able to fix
the worst of the problems (except maybe the lack of AA fonts and i18n)
and survive until we get a replacement.
