This looks very weird. If it's calling EVP_Cipher, that should go through OpenSSL; it's conceivable that it might end up in libkeyutils via the Kerberos libraries, sure, but a simple cipher call should already have everything it needs; and libkeyutils doesn't use D-Bus.
Could you attach /lib/x86_64-linux-gnu/tls/libkeyutils.so.1 so that I can see if I can make anything out of the offsets in your perf output?
