I reproduced it and will commit a fix.
In the meantime, please set a picture wallpaper manually from Ubuntu's Appearance (NOT a color or gradient). This should allow you to launch it.

[Bsienn (bsienn)]

Thanks 4 response. desktop already a wallpaper not a gradient or solid color.
Craches even with ubuntu's custom background wallpaper.

[Peter Levi (peterlevi)]

Are you on Unity or some other DE?

[Bsienn (bsienn)]

I am on Unity. Default fresh Ubuntu Install.

[Peter Levi (peterlevi)]

I wonder why the get_wallpaper script exits with an error.
Please try running "gsettings get org.gnome.desktop.background picture-uri" in a terminal.

[Bsienn (bsienn)]

sorry 4 late reply, the time-zone differs. here is the output of the command:
'file:///mnt/882C04092C03F14C/My%20Gallery/Wallpapers/Desktoppr/_166_.jpg'

i opened a picture in viewer from same directory and ran the same command and got this:
'file:///home/bsienn/.local/share/eog-wallpaper.jpg'

after doing each step, i got that same error.

i did a purge and deleted the variety congif file from /.config/variety folder.
reinstalled and same behavior.

[Peter Levi (peterlevi)]

I committed a fix, please confirm that the problem is fixed in the attached version.

[Bsienn (bsienn)]

I am so glad it got fixed. thanks a lot Mr Peter Levi. Just tested and it working good. I hope the Ubuntu up/down scroll to chnage wallpaper gets fixed as well. its been too long.

Thanks.

Regards
Bsienn Khan

[Peter Levi (peterlevi)]

Re: up/down scroll. Actually I got in touch with the correct people there and a fix for this is already committed and released in the trusty-proposed repository. Please help verifying that the bugfix works, instructions are in this comment: https://bugs.launchpad.net/ubuntu/+source/libappindicator/+bug/1071738/comments/14

[Peter Levi (peterlevi)]

Bsienn, can you help me debug why get_wallpaper fails?

The current fix fixes the Python side of the code, but we still don't know why and where get_wallpaper exits with a Segmentation fault (/home/bsienn/.config/variety/scripts/get_wallpaper: line 38: 3505 Segmentation fault (core dumped))

Please edit ~/.config/variety/scripts/get_wallpaper and put some debugging "echo 111", "echo 222", etc. statements between the commands around line 38 and run it so that we see exactly which command causes the error. Then once you pinpoint it, please run it separately in a terminal to check what happens. Thanks.

[Bsienn (bsienn)]

I'll be very delighted to help with it. as soon i get back to my ubuntu box
i'll try ur suggestion.in about in 1 or 2 hours.
as far as i am understanding, i have to purge previous install and dell
variety config & install a previous version.
or will the default command will install the bugged version?

sudo add-apt-repository ppa:peterlevi/ppa
sudo apt-get update
sudo apt-get install variety

The scroll patch fixed he scroll issue with (libappindicator )
but the picture in enable proposed is old. my 14.04.1 ubuntu unity had different options.
i had to check the (pre-release something option) and it updated the (libappindicator ) and the scrolling is working great.

[Peter Levi (peterlevi)]

No need to reinstall anything for now, the Beta version uses the same get_wallpaper script. Just run it (the full path is ~/.config/variety/scripts/get_wallpaper) and make sure it gives Segmentation fault like before.

[Bsienn (bsienn)]

since the comit u made, i cannot replicate the error.
i was trying to install a previous verion but i am unable to do so, bcoz i didn't found how to do that. and i am very new to linux as well.

i ran the script get_wallpaper and it executes normal returning the uri of wallpaper.
