How to reproduce

Have a transparent text clip

Duplicate the text text clip

Double click for newly created clip properties

In clip properties rubbish is displayed on background, this should be fixed too

Make alterations, change name, preferably, click OK

Kdenlive will crash immediately or soon

Crash replicable: not always but most likely

No accelerated IMDCT transform found

Now it crashed even sooner, Just duplicate text clip and double click on it.

P.S.

The same sources as before

I made a few fixes, can you please try with updated svn version ?

regards

Seems to be fixed
