Consumes gigabytes of memory when previewing mp3

[Skylar Ittner]

When I import an mp3 file, right-click, and select "Preview File", OpenShot starts using gigabytes of memory. It increases at a rate of 1GB every 5 seconds or so. The memory stays in use after stopping the playback, and is only released when I close OpenShot.

I installed OpenShot today from the Ubuntu PPA (version 2.1.0).

I've attached a public domain mp3 file that causes this for me. Neither ffplay nor melt seem to have a problem with the file.
