[Bug 1811641] Re: Wodim permissions error: /usr/bin/wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.

@Chris Guiver Thank-you for taking the time to respond to this bug
report!

I've done some upgrades, since I posted the original report, but after
uninstalling and reinstalling K3B and Wodim, the symptoms are the same
(partial log output, with error, below).  The "chmod +r /usr/bin/wodim"
trick still functions effectively as a workaround.  Please let me know
if you need anything else.
