[Bug 2080004] [NEW] Shotwell bug - Out of memory #5123

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Nathan Teodosio (nteodosio):

Impact
------

A memory leak that will cause Shotwell process to increasingly eat
memory constantly during a slideshow.

Test case
---------

*Start Shotwell and import a folder with about 10 photos; End Shotwell.

*Save this script as tester.sh:

--->
#!/bin/sh
shotwell &
pid=$!
statm=/proc/$pid/statm
time=0
inc=1

while test -e "$statm"; do
    stack=$(cut -f6 -d' ' "$statm")
    printf "%s %s\n" "$time" "$stack"
    sleep "$inc"
    time=$((time+inc))
done >> "$pid.dat"
<---

*Execute it.

*Press F5 to start slideshow and keep pressing right arrow to cycle
through the photo set about 3 times.

*End Shotwell.

Expected: The memory logged in the PID.dat file stops increasing instead
of steadily and indefinidetely increasing.

You can use "xmgrace *.dat" to get a plot of the behavior before and
after the fix for easier visualization (see attached shotwell-stat.png).
