svn client seg faults against https repositories 
svn (1.7.7) gave nothing but segmentation faults when trying to update or checkout repositories over https.
the culprit is an incompatibility between gnutls-3.1.4 (or gnutls-3.1.3) and neon-0.29.x
Downgrading to gnutls-2.12.20, and then re-emerging neon and subversion fixed it.
