Kdenlive Crashes oin start up

[Douglas Pollard]

I am making a video of mostly pictures and some Video. When Kdenlive it 
starts for a couple of seconds and then crashes.  I opened kdenlive in 
the Terminal and below is the error.   I guess this error is shutting 
the program down?  Can someone help with a solution?  This is the last 
entry so am guessing this is the problem. I have a 30 minutes of video 
not far from finished so don't want to loose it.   Thanks for any help I 
have little Knowledge of terminal use so will need a detailed solution 
if possible.   Doug Pollard
