[redland-dev] Re: Rasqal segfault

[Danny Ayers]

This (as suggested on the site ;-) appears to have done the trick,
on Redland itself:

make clean
rm -f config.cache

then reconfiguring etc.
I hit the exact same problem on both my local and remote servers (deb
unstable), but that's not such a surprise, they're set up nearly
identically...

ORDER BY! Fun time!

Cheers,
Danny.
