I'm using version 0.9.4 (and 0.9.5 from PPA sources) on a Ubuntu Studio 12.10 system. Aside from occasional non-destructive crashes I've had good results using the program, with the exception of the internal title clip editor. It consistently causes Kdenlive to freeze, especially if I try to select a font. I'm using the Gimp as a title editor, but I do wonder if it's something I'm doing wrong. Any suggestions?
