inkscape in rawhide segfaults immediately on start up

[Richard W.M. Jones]

I haven't looked into this in great detail yet, but I wonder if this is 
a known problem?  There is no bugzilla that I can find and it's a 
complete show-stopper so I can't imagine how it got past even the most 
minimal test.

Rich.
