On some systems (e.g. x86_64 linux) midori crashes when
trying to visit "about:version".
The crash happens in some printf function deeper in the
call stack. But I have a theory that much stack space is
occupied already before calling g_strdup_printf. I have
not analyzed the situation more closely.
This fixes the crash by splitting the generation of the
version information page into multiple calls. If my theory
is correct, it should now only work because I reduced peak
stack usage.
