Hello,

thanks for the report. wget links both directly and indirectly against
nettle (direct: libnettle4, indirect via gnutls: libnettle4 in
unstable, libnettle5 in experimental). Since nettle < 3.1 does not use
versioned symbols this causes a segfault.

nettle 3.1 provides versioned symbols but that does not help for
the pending transition. A wget binary linked directly against
libnettle4 (unversioned) and indirectly (via gnutls) against
libnettle6 (versioned) still crashes.

This needs changes on the nettle side of things, but I will keep the
bug-report open here.

Looks like we need a two-step transition: nettle 2.7 -> nettle
2.7+versioned_symbols , nettle 2.7+versioned_symbols -> nettle 3.1.

cu Andreas
