No longer happens with the kdenlive-17.08.3 and mlt-git-955f19c.

I guess it's been fixed by the following commits, however I haven't verified
this theory:
https://github.com/mltframework/mlt/commit/21c21620268725e63e699df77cf886f518c5b0f9
https://github.com/mltframework/mlt/commit/9e9a86a1214585259868448ba8477655e93d993c

Old project producers will lose one frame from converting to v6.5.0 format
(00:00:26;29 is now containing a number of
frames instead of a string length), however they will not lose any frames going
forward.

Hi Jean-Baptiste,

Could you please try my latest example and let me know if you're able to repro?
Only steps 1-4 are needed to see whether it reveals the problem.

Thanks,
Nikita.

Created attachment 108725

example for the kdenlive-17.08.2-x86_64.AppImage

Reproducible but with a slightly different example:

Steps that I made:
1. Open AppImage (HD 1080p 29.97 fps project)
2. Add clip3.mkv to the project bin - you'll see 00:00:27;00 length.
3. Save the project to frame-count-bug-example3.kdenlive and close AppImage.
4. Open AppImage and open frame-count-bug-example3.kdenlive - you'll see
00:00:26;29 length.
5. Save As... frame-count-bug-example3_save1.kdenlive and close AppImage.
6. Open AppImage and open frame-count-bug-example3_save1.kdenlive - you'll see
00:00:26;28 length.
7. Save As... frame-count-bug-example3_save2.kdenlive and close AppImage.

Expected Results:  
00:00:27;00 length from the start and not changing on re-open.

I just tested with MLT git and latest Kdenlive (17.08.2) and cannot reproduce
the problem. Can you test if your issue is reproducible for you with our stable
AppImage: https://kdenlive.org/download/

Reopening as it's happening again. mlt-6.4.1. kdenlive-17.08.2. Could be
reproduced on the original example.

Ok, I've found the reason. It's mlt v0.9.8. Upgrading to v6.2.0 fixes the
issue. I was stuck with old mlt version due to bug #364891, however JBM
suggested a workaround and now I can move forward.

Kindly ping. This bug currently blocks any video editing on my side since a
timeline becomes corrupted if you simply re-open a project.

Wegwerf, I checked that the problem is still exists in version 16.04.2.
Can someone follow the steps and see if it's reproducible on your end?
