[redland-dev] Redland 1.0.1 Segfault

[Danny Ayers]

I've been getting segfaults too on queries (through Python), but I
suspected the problem was in my install (I'm still learning the Linux
system). They were happening with the code from cvs from a couple of
weeks ago, but yesterday I stripped all that out and installed the new
Redland+Bindings releases.

I don't have any repeatable examples (I'll try the source below in a
minute) or traces yet,  I'm running the queries through mod_python -
all I can see right now is one line in Apache's error log.

Cheers,
Danny.
