Problem with Subversion + Neon + GnuTLS 2.5

[Arfrever Frehtes Taifersar Arahesis]

I have Neon configured with the --with-ssl=gnutls option. I use
Neon trunk r1531 and Subversion trunk r32513. I recently upgraded
GnuTLS from 2.4.1 to 2.5.3 and now when I try to use Subversion
(which uses Neon) with https:// protocol I get this error:

Ohhhh jeeee: operation is not possible without initialized secure memory
Aborted

This error doesn't happen when I use ra_serf instead of ra_neon.
This error also ceases to happen after downgrading GnuTLS to 2.4.1.

Is it a bug in Neon or in GnuTLS?
