Hello, i m getting a segmentation fault everytime i try to do anything with a sofia profile, for example everytime i try to rescan or start a profile. Analysing the core dumped the problem seems to be in "switch_ci_hashfunc_default": Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". Core was generated by `freeswitch'.
