[SR-Users] Segmentation fault Dialog RPC

Hi all, i'm using kamailio 4.4.6 , and when I call the rpc dialog "profile_list_dlgs" , sometimes I have a segmentation fault. Can you help me to understand why it happened ? Thanks to all. This is the dump: Program terminated with signal 11, Segmentation fault. #0 0x00007f49ee062e07 in internal_rpc_print_dlg (rpc=0x7f49ed99e9c0, c=0x7f49ed99e960, dlg=0x7f49ef89ba38, with_context=0) at dialog.c:1548 1548 if (pl->profile->has_value) { Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.192.el6.x86_64 keyutils-libs-1.4-5.el6.x86_64 krb5-libs-1.10.3-57.el6.x86_64 libcom_err-1.41.12-22.el6.x86_64 libselinux-2.0.94-7.el6.x86_64 libxml2-2.7.6-21.el6_8.1.x86_64 lua-5.1.4-4.1.el6.x86_64 mysql-libs-5.1.73-7.el6.x86_64 nss-softokn-freebl-3.14.3-23.3.el6_8.x86_64 openssl-1.0.1e-48.el6_8.3.x86_64 zlib-1.2.3-29.el6.x86_64 (gdb) bt full #0 0x00007f49ee062e07 in internal_rpc_print_dlg (rpc=0x7f49ed99e9c0, c=0x7f49ed99e960, dlg=0x7f49ef89ba38, with_context=0) at dialog.c:1548 rpc_cb = {rpc = 0x3031ea0, c = 0x400} h = 0x2d21e60 sh = 0x2d1db70 ssh = 0x2d20050 pl = 0x7f49ef18c588 var = 0x0 __FUNCTION__ = "internal_rpc_print_dlg" #1 0x00007f49ee0637b3 in internal_rpc_profile_print_dlgs (rpc=0x7f49ed99e9c0, c=0x7f49ed99e960, profile_name=0x7fff65fcb1a0, value=0x0) at dialog.c:1681 profile = 0x7f49ee5aca88 ph = 0x7f49eeb5b670 i = 2 #2 0x00007f49ee063e64 in rpc_profile_print_dlgs (rpc=0x7f49ed99e9c0, c=0x7f49ed99e960) at dialog.c:1785 profile_name = {s = 0x3031e80 "outbound", len = 8} value = {s = 0x0, len = 0} #3 0x00007f49ed78960f in jsonrpc_dispatch (msg=0x7fff65fcc5a0, s1=0x0, s2=0x0) at jsonrpc-s_mod.c:1098 rpce = 0x7f4a13212d30 ctx = 0x7f49ed99e960 ret = 0 nj = 0x3031ab0 val = {s = 0x3032030 "dlg.profile_list", len = 16} __FUNCTION__ = "jsonrpc_dispatch" #4 0x000000000041f75d in do_action (h=0x7fff65fcc4c0, a=0x7f4a13189e28, msg=0x7fff65fcc5a0) at action.c:1054
