unable to separate video and audio by using "ungroup clips" button

[Experimenter]

unable to separate video and audio by using "ungroup clips". On clicking "ungroup clips' button nothing happens
ver 0.15.2-0ubuntu0.1 in 12.04 LTS

Below is the traceback thrown on clicking ungroup clips

A quick fix is attached as a patch that comments line 162 in /usr/lib/pitivi/python/pitivi/ui/clipproperties.py that tried to reset the zoom to 1. The patch does not adversely affect the program in any other way.

Experimenter,

Thanks for the patch I was testing it out and there were some errors with self.effect = None although it did ungroup the clips but for some reason that portion of your patch appears to cause some instability and requires a force quit.

Have you had the same results with your patch?

[Experimenter (experimenter)]

I have not experienced any problems with the patch.
There is only 1 change in the patch @ line 162 in
/usr/lib/pitivi/python/pitivi/ui/clipproperties.py

   - self.zoom_scale.set_value(1.0)
   + #self.zoom_scale.set_value(1.0)

kindly try adding the change manually.
also verify if you are using the ver 0.15.2-0ubuntu0.1 in 12.04 LTS

Regards
Experimenter

Excuse me for the mistake.. The patch is at line no 609 and not 162 of
the file
change in the patch @ line 609 in
/usr/lib/pitivi/python/pitivi/ui/clipproperties.py

   - self.zoom_scale.set_value(1.0)
+ #self.zoom_scale.set_value(1.0)

I tried the patch on a different machine and it is working fine there too.

The updated patch should solve your problem. I realized that zoom
setting might be important for some effects. The new patch just catches
the exception if it occurs and the program flow resumes.
please remove the previous patch before applying this.
