Hello! Bluez bluetoothd daemon compiled from git master branch crashes when I try to call DBus method for switching A2DP codec. Below is stacktrace from gdb. It looks like NULL pointer dereference. It is reproducible. Program received signal SIGSEGV, Segmentation fault. 0x000055e1b3659c1a in avdtp_find_remote_sep (session=0x55e1b408bf80, lsep=0x0) at profiles/audio/avdtp.c:1221 1221 if (lsep->info.inuse) (gdb) bt #0 0x000055e1b3659c1a in avdtp_find_remote_sep (session=0x55e1b408bf80, lsep=0x0) at profiles/audio/avdtp.c:1221 #1 0x000055e1b36568fc in find_remote_sep (sep=<optimized out>, chan=<optimized out>, chan=<optimized out>) at profiles/audio/a2dp.c:1169 #2 0x000055e1b3656955 in a2dp_reconfigure (data=0x55e1b40a1e10) at profiles/audio/a2dp.c:1188 #3 0x00007f4e07e90863 in ??
