Render Error Window.

Just installed 18.04.1 on Windows 10 (v1803, 17134.228) and cannot render anything. 

Went to render from a previous project with the default Mp4 settings and receive the following error:

----------------------------------------------------------------------
"melt"

This application failed to start because it could not find or load the Qt platform plugin "windows" in "".

Available plugins are: minimal, offset, windows.

Reinstalling the application may fix this problem.

Update win10 and update the graphic card driver as well.

Then download the actual version 18.08.0 from here: https://files.kde.org/kdenlive/release/Kdenlive-18.08.0-w64.7z

As you know, you don’t have to install. Extract it to a separate folder and try again.

I deleted everything in APPDATA (Win+R) and it worked.

Btw this happened after I updated from 17.12, then to 18.04, then it 18.08.
Jean Baptiste Mardelle please can you take a look into this and make sure it doesn't happen? I didn't know that you could log to file back then

Maybe we can better handle the Kdenliverc files to avoid this issue.

This problem should be solved with 20.08.1 as Kdenlive checks if the path is correct set to MLT. 

We close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
