Confirmed.  And the Apache log is full of these:

/var/www-sugarlabs/wiki/bin/ulimit4.sh: line 4: 25357 Killed
      '/usr/bin/convert' -background white -size 120
'/var/www-sugarlabs/wiki/images/2/2d/Basic-sugar-boot.gif' -coalesce
-thumbnail '120x120!' -depth 8 '/var/www-sugarlabs/wiki/images/thum
/2/2d/Basic-sugar-boot.gif/120px-Basic-sugar-boot.gif' 2>&1

Because it happens with *all* images, perhaps ImageMagick is broken.

It's ImageMagick, not PIL, but I'll have a look.
