Thanks a lot for this backtrace, this helps to locate the issue. It seems that strcasecmp() is called with the second argument being NULL in conf_get_tag_list() at at conffile.c:582. This would point to a bug in the mount.nfs binaries. However to fully confirm that, would it be possible to rerun the same procedure after installing the libc6-dbg package? That should give more details about what happens in strcasecmp(). Regards, Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
