A couple of comments on segfaults under 64-bit amd64 systems.  What I've
found in sodipodi and other Gnome/GTK programs is variable argument list
functions that are supposed to be NULL pointer terminated being 0
terminated instead.  I filed a bug report and patch with Gentoo about

This might be worth checking in Scribus as well, if you're seeing amd64
crashes in program code that works fine in x86.

Look in the Gnome/GTK library headers for functions defined with ...,
and check that their arguments are all properly typed.  The compiler
cannot typecast arguments in varargs calls since it doesn't know what
the arguments are supposed to be.

This is all assuming that you're interested in fixing the code
yourself.  At least with Sodipodi if you're seeing the bug I found (a
crash when inserting text), the fix should trickle down eventually.
