The most important part of the backtrace - frame 0 - is missing.
If you can reproduce it, is the new core printing the same kind of backtrace, with fame 0 not showing relevant information?
If yes, can you try with debug=3 in kamailio configuration file and paste here the logs message while executing the http query?
