Synaptic Package Manager Crashes After Changing Icon Theme

I installed a new iconset (Areao 43) and dark theme for Ubuntu, but soon after that Synaptic Manager kept crashing on entering the password.

After researching a bit and checking different solutions (one of them being http://ubuntuforums.org/showthread.php?t=1854470&p=11343209#post11343209) I realized that the iconset was the problem. After trying out different things I was able to figure out a fix for this particular issue.

1. Open a Terminal (Ctrl+Alt+T)
2. Open Nautilus with superuser permissions by typing the following and entering your password :
   sudo nautilus
3. Go to the icon folder
   /usr/share/icons/<insert icon folder name>
4. Open the file index.theme with a text editor (I use Kate)
5. Look for the line that starts with Directories =
   Directories=scalable/actions,scalable/apps,scalable/categories,scalable/devices,scalable/emblems,scalable/mimetypes,scalable/places,scalable/status,scalable/stock
6. Add ,16x16/gtk at the end if it is not there in the line (don't miss the comma)
7. Go to the end of the file and paste this code
   [16x16/gtk]Size=16
8. Search any other icon folder in this location (/usr/share/icons) for a 16x16 folder, copy the entire folder and its contents, come back to the original icon folder mentioned in point 3 and paste it there
9. Save the file and close

Synaptic package manager should now work. Apparently there is a dependency on 16x16 icons along with scalable icons.
