SUMMARY
I have a project with 8 sequences, each having subtitles and 2-4 video tracks and 2 audio tracks.

During the last few days I created these sequence one after the other with subtitles being ok.
Today I edited a subtitle when kdenlive crashed - I started from the latest backup kdenlive offered. 
And a bit later I recognized, my subtitle vanishing. Quitting and re-starting kdelive made it even worse.
Even in the backup version there a no subtitles anymore.

I cannot tell the steps to reproduce the crash.
BR Matthias
