[redland-dev] Rasqal segfault

[Danny Ayers]

I spoke too soon - I had applied the last patch.

I'd got Redland (R&R internal) plus bindings latest versions, so did
make uninstall on those before configure, make, make install latest
Raptor, Rasqal, Redland, bindings. I don't /think/ the version wires
have got crossed.

Here's what I got:
