15.12.3 I cannot work, KDE shutdown all the time. Il's the first time it make this.
From my user experience, Kdenlive makes a huge stability step from 15.08 to 16.12.3. Please, upgrade to supported version (I had to buy a new graphic card because my radeon graphic card wasn't correctly supported by new linux kernel, but now, I working with Kdenlive is a pleasure!).
Hi bellier, you are using a very old version of Kdenlive, please update. Here is how to get the latest version on most distros: https://kdenlive.org/download/
It seems the problem is solved. I closed this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
