[OpenSIPS-Users] mediaproxy segmentation fault

Tue Oct 18 18:23:54 CEST 2011

This problem was caused by a debian bug on the libgcrypt11 package for
wheezy/sid (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=643336) to
solve it one must downgrade to version 1.4.5-2 from squeeze (can be
downloaded from
http://ftp.us.debian.org/debian/pool/main/libg/libgcrypt11/libgcrypt11_1.4.5-2_i386.deb).
I used dpkg without problems for this.  It seems that this only happens on
i686 architecture (I'm working with wheezy).  Special thank to Saul for his
help on this issue.
