[Csync2] csync2 client core dump on ubuntu 12.04

[Michi Mutsuzaki]

Hi,

I'm using csync2-1.34-2.2build1 on ubuntu 12.04, and I'm seeing
occasional core dumps. The stack trace looks something like this:

Core was generated by `csync2 -x -N dfdf96d7-979c-44ba-b58e-1a1e5afe3a69'.
Program terminated with signal 6, Aborted.

Here are the versions of gnutls related packages:

libgnutls-openssl27 - 2.12.14-5ubuntu3.1
libgnutls26 - 2.12.14-5ubuntu3.1

Has anybody seen a trace like this?

Thanks!
