Comment 51 for bug 155032

The current version of kdesudo in gutsy and hardy does not need root-write access to $HOME.
The kdesudo version released in the first gutsy, did however start programs as root, but with the users environment variables.
This evil and ugly bug told programs like adept, dolphin, konqueror and others,
to save their configuration files to the users $HOME/.kde/ folder,
even when the programs actually were running as the root user.
The result is root-owned files in the users home directory once a program is executed with kdesudo.
This issue is fixed in the ubuntu2.2 version in gutsy and in the hardy version.

One should check the user home directory for root-ownership on configuration files, as that can be frustrating.
Saving new configurations, bookmarks, settings etc. as the user might not work at all, if this is the case.
