Dear Maintainer, hello Anthony DeRobertis,
I just tried to reproduce this issue in a buster amd64
qemu VM with a uptodate buster at 2018-09-27.

Package: clementine
Version: 1.3.1+git565-gd20c2244a+dfsg-1
Severity: normal
I'm not sure if this is a Clementine bug or a Gstreamer bug, but I've
noticed that when I leave Clementine running for a bit, its memory usage
grows massive (many GiB). I'm playing almost exlusively FLAC files,
which all have (fairly large) embedded artwork, multiple images per
file.
I used heaptrack to attempt to track down where the memory leak is. This
is after only a day or two of use:

I could just get a backtrace with debug symbols that
looks very similar to Anthonys call stack from heaptrack:

(For some reason heaptracks locations 3 last digits are one lower than gdbs?)
Unfortunately I never received a heaptrack report that
shows this allocation as leaked on my test system.
Was this a different heaptrack version or I just used it wrong?
Also a valgrind run did not show a leak at this location.
I have no idea why that backtrace doesn't show any Clementine code in
it. I tried installing some more -dbg/-dbgsym packages, but maybe I had
to do it before starting Clementine.
Heaptrack may be not prepared to use the debug information
delivered by the dbg packages. I also got no stacks from heaptrack
files record while dbgsym packages were installed.
Note this is the main clementine process, not the tagreader processes:

While playing I could not see an increase of memory usage percentage in htop.
Following is the location where the memory allocated in given
stack was freed in my test system:

Attached a file with some details on my debugging and the input file used,
maybe that has a special content.
Possibly you can track it down to a single file and provide the
output of mediainfo of that file.
Kind regards,
Bernhard
