So I now finally saw this for one of my projects too, so I'm confirming.
However, this is not reproducible at 100% and it does not happen to all
projects, but only to some.

How to reproduce (hopefully): this is a freshly created project where I render
the timeline into several parts (using guides). I then add several rendering
jobs from the same project to the job queue, and at the same time explicitly
start all rendering jobs so they run in parallel. Typically, from 6 or 7
rendering jobs running in parallel, at least 1 or 2 get stuck at the final one
or two seconds, despite the rendering having finished properly as I can see
from the final video file. In addition, the .txt MLT render XML input files
never get correctly cleaned up; this happens to both finished and hung jobs.
The hanging jobs were running for several minutes, so this happens not only to
quick jobs.

video file to be used in reproducing the bug

I am running into this occasionally (perhaps 50% of the time I render). Here is
how to reproduce:
1. Import the attached video into the project bin, then put it on a video track
(I put mine on "Video 1").
2. Click "Render" and for the format, select Generic -> WebM and keep the
default options.
3. Click "Render to File".

Result: If it tells you that rendering is completed, clear the job and render
again, opting to replace the file when prompted. On my system, it only takes
2-3 renders before the render eventually stalls at 99% completed.

If you check the end of the rendered video's accompanying text file, it will
say that rendering was finished, and the video file seems to be complete.
However, the "unfinished" job will be hung up in Kdenlive's queue, unresponsive
to any requests to end or abort the render.

When running Kdenlive from the command line, there is no difference in terminal
output between a successful and a stalled render.

I was able to repro this bug in the following configurations that I tested:
#1, via KDE Neon repository:
 . Kdenlive 16.08.2
 . KDE Frameworks 5.27.0
 . Qt 5.7.0
 . MLT 6.0.0

#2, via devel AppImage:
 . Kdenlive 16.11.70 (devel)
 . KDE Frameworks 5.27.0
 . Qt 5.7.0
 . MLT 6.3.0

Both of these versions were tested on the following system:
 . OS: KDE Neon 5.8.2 64-bit (Plasma Desktop 5.8.2)
 . PC: HP Pavilion m6-1035dx
 . CPU/GPU: AMD A10-4600M APU with Radeon HD 7660G Graphics (using xorg radeon
driver)
 . RAM: 6GB DDR3 800 MHz
 . Linux Kernel: 4.4.0.45-generic

Cannot reproduce, and I'm doing a lot of projects with Kdenlive, where I render
to MPEG-4 containers. What distribution and desktop environment are you using?
I remember that we had once an issue where the completion wasn't been correctly
detected, but this has been fixed quite some time ago. Could the Neon packages
be stale??
