I had this issue too.

Having the same problem today. Also tried in a second computer wich runs Fedora and the same error is showing. Looks like it is not only affecting Ubuntu.. In my case, I was trying to record an audio CD.

I'm experiencing the same problem with Ubuntu 18.04 release. I tried to disable the wodim plugin but the check box is checked and gray. I tried setting the USID bit in /usr/share/bash-completion/conpletions/wodin but the brasero crash still occurred. Tested on two different computers.

[Bug 1764096] Re: Brasero can't burn DVD because of permissions issue
Hi,
the first message about lack of permissions is common and should be
harmless. The failure happens possibly with the attempt to get 16 MiB
of memory via call mmap(2). But it is not obvious why this only succeeds
if you are superuser.
So this might too be a red herring and the actual reason for wodim to
abort is something that is not reported.
The last messages about "HUP" probably say that wodim closed the pipes
by which it was connected to Brasero. Not necessarily the reason but
rather a consequence of the problem.
The reason for the mmap error message is probably
addr = mmap(0, mmap_sizeparm(size),
PROT_READ|PROT_WRITE, MAP_SHARED, f, 0);
where "f" points to /dev/zero.
(https://sources.debian.org/src/cdrkit/9:1.1.11-3/wodim/fifo.c/#L272)
The man page of mmap says about the error EAGAIN ("Resource temporarily
unavailable"):
EAGAIN The file has been locked, or too much memory has been locked
(see setrlimit(2)).
man 2 setrlimit points to prlimit(1). But running it shows no mmap specific
limiting parameter other than "MEMLOCK", which would only matter if flag
"MAP_LOCKED" was used with the mmap() call.
What do you get from this command:
cat /proc/sys/kernel/shmmax
(Mine says 18446744073692774399. I.e. no real limit.)
What permission do you see with
ls -ld /dev/shm
As a workaround for non-superusers you could switch in Brasero from
the wodim plugin to the libburn plugin. It is supposed to use a slightly
different mmap() call when allocating its fifo buffer.
Have a nice day :)
Thomas
