Hi Nico, I tried to reproduce the issue but couldn't. Exactly how are you sending the requests? I've tried both curl and hand-typing over gnutls-cli.
If you still have this issue, could you try enabling the appropriate debug repositories (see https://wiki.debian.org/AutomaticDebugPackages) and installing the relevant *-dbgsym packages to see which functions loop in the backtrace? I assume you'll need at least these: apache2-bin-dbgsym libapache2-mod-gnutls-dbgsym libgnutls30-dbgsym Best regards, Fiona
