Unfortunately, the `libell.so` I have (from Arch's [extra-testing] repo) 
wasn't compiled with debuginfo, so all the backtrace I have is:

#0  0x00007ffff7f22de6 in l_netlink_send () from /usr/lib/libell.so.0
#1  0x000055555556d53d in ?? ()
#2  0x00005555555ae380 in ?? ()
#3  0x00007ffff7f25b95 in ?? () from /usr/lib/libell.so.0
#4  0x00007ffff7f203cb in ?? () from /usr/lib/libell.so.0
#5  0x00007ffff7f20655 in l_main_iterate () from /usr/lib/libell.so.0
#6  0x00007ffff7f20ace in l_main_run () from /usr/lib/libell.so.0
#7  0x00007ffff7f223a4 in l_main_run_with_signal () from 
/usr/lib/libell.so.0
#8  0x000055555555fd13 in ?? ()
#9  0x00007ffff7d0ee08 in ?? () from /usr/lib/libc.so.6
#10 0x00007ffff7d0eecc in __libc_start_main () from /usr/lib/libc.so.6
#11 0x0000555555560575 in ?? ()

I will try to compile it with debuginfo and get the backtrace.
