Uses all memory when navigating

[tlc]

I recently upgraded to your 5/9/2018 commit via git pull. When navigating to a certain directory of .mp4 files, pyTivo quickly consumes all free memory (~6 of my 8 gig) on my Ubuntu 16.04 machine. I watch it with htop, it takes only a few seconds.

This directory contains files I've captured off a live stream.

The memory problems happens when I enter the directory, not transferring a file.
I moved the .meta directory and verified that it happens with just the .mp4 files.

I am attaching the output of ffprobe on one of the files. probe03.txt

I pulled the 1/1/2017 version and it happened with that one too.

I tried leaving individual files in the directory. The probe of the file that causes it is linked above. This is a diff of that probe with one from a similar file that does not cause the problem.

The "03.mp4" file below is the problem one. It has a higher bitrate. The file plays OK in VLC.

$ diff probe0?.txt
