thanks for the quick response... well.. it is sort of a clean trusty install. but.. with the first things being installed are kerberos and some pam modules ;-) Your remark about the pam module makes sense.
in short.. I installed the debug symbols of packages that interested me. Installed dbg and setup sshd on a different port. started a new ssh session, started the debugger and attached it to the process serving my new session. added a breakpoint on global_init and logged in with the session.. the breakpoint was hit ;-) below the backtrace. so I guess I found the module responsible for this.. unfortunately I was not able to find any debug packages for libpam-ccreds (version 10-6)... so how to continue.. is there any way I can get the debug symbols for this package and narrow down to the functions being involved? or is this information below enough? #0 global_init () at global.c:100 #1 0x00007f6e26a991b1 in _gcry_global_is_operational () at global.c:169 #2 0x00007f6e26a97c31 in gcry_md_open (h=0x7fffd2ab1d08, algo=2, flags=0) at visibility.c:771 #3 0x00007f6e26d0fa3e in ??

From looking at the above patch, it does not seem to do any harm, since the lib will then initialize itself. When trying to find issues on a system, warnings like this will make things a bit more cloudy then needed. A proper implementation for this would be beneficial to the system in general. These warnings are present in 14.04.
