No video after choosing any effect other expect "no effect"
After I chose any effect other effect than "no effect" cheese shows no video. Instead the message "Ein Fehler ist beim Abspielen des Webcam-Videosignals aufgetreten" ("There was an error playing video from the webcam") Even if I start the App again, no video, the same message. The workaround is to call dconf-editor and choosing "Vorgabewerte verwenden" ("Use default value") so that "identity" is used. I startet strace cheese with the attached output, where I clicked on "Effekte" three times. The first time it took 25 seconds, until the preview videos of 9 effects were shown (kein Effect, Aufblähen, Ecken, Historisch, Hulk, Kaleidoskop, Kung-Fu, Optische Täuschung and Psychedelisch"). The first two times I have choosen "kein Effekt" (no effect) and the normal video returned. The third time I have chosen another effect and the original video appearded for less than a second and then I got a black video screen with the error-messege, which I can only get rid of by calling dconf-editor. My system is openleap 15.1, all updates installed, cheese version is 3.26.0 cheese.strace
