bspc control --subscribe will crash when unplugging external monitor

[ghost]

For me bspc control --subscribe will crash, if I disconnect my external monitor from my laptop with the option 'remove_unplugged_monitors' set to 'true'.
It has to be something within the last 10 commits! Before those it is working fine here.

Don't really know, what log files to append, because it just stops without throwing an error message. Exit code is 0.

EDIT: Forgot to mention I use xrandr --output DP1 --off to disable the monitor after disconnecting

gdb backtrace?

Tried to get the stack of bspc control --subscribe with gdb, but as soon as I disconnect the monitor it will crash and I can't really log the stack. Maybe you got a hint how to log this?

dmesg tells me this:
bspwm[28867]: segfault at 20 ip 0000000000410854 sp 00007fffc054cec0 error 4 in bspwm[400000+15000]

The last message I get is (which should be ok):
WMeDP1:FDesktop1:LT:mDP1:FDesktop2:LT

I added if (m != NULL && m->desk != NULL) in line 90 of subscribe.c before the fprintf and the problem seems to be fixed!
At least it isn't crashing for me anymore

Tried to get a system-coredump, but failed.
Seems like it is not creating one when crashing.

It should be fixed by 1e0a7c8.

Seems to be working.
Thanks!
