That's perfect.  A disk (due to rules dating back to at least the XT and
DOS) can only have 4 _Primary_ partitions.  When it was discovered that
perhaps 4 wasn't enough (approximately the same time we found 640K wouldn't
do for memory).  So they created "Extended" partitions that can contain
other "Logical" partitions.  Your setup has 3 Primaries, 1 Extended, and
then 1 Logical inside the Extended.  

So then you should be able to simply change the lines in /etc/fstab:

# /dev/sda5
UUID=52810d5c-61ab-4942-afa2-9e6e953f839d none swap    sw 0 0

to 
/dev/sda5 none swap    sw 0 0

(use sudo to edit it if you want to use a non-GUI editor like nano, or
kdesudo to edit it in a gui like kate)

Finally, "sudo swapon -a" should turn on your swap.

Ah!  I suppose that's one of the hazards of your job.
