from htop - take a look at RES as time goes by:
PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command
34613 lightdm 20 0 665M 216M 8792 S 27.2 0.1 3:48.53
/usr/lib/x86_64-linux-gnu/indicator-keyboard-service --use-gtk
a little later
PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command
34613 lightdm 20 0 697M 248M 8792 S 26.1 0.1 5:38.43
/usr/lib/x86_64-linux-gnu/indicator-keyboard-service --use-gtk
and again later
PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command
34613 lightdm 20 0 783M 307M 8796 S 0.0 0.1 10:23.49
/usr/lib/x86_64-linux-gnu/indicator-keyboard-service --use-gtk
this is roughly 50% growth. Probably not required for this
application...
The thing is that I noticed this this this morning because RES actually said:
12.8 GIG. *zomg*
That seems excessive for a keyboard indicator.
It appears to be reading the same file over and over and again but
perhaps not doing so correctly.
Using strace we can see that while there are just as many munmap as
mmaps:

So perhaps it is leaking with more traditional mallocs.
In any event, over time, this thing consumes massive quantities of memory,
which is probably a bug.
