Comment 97 for bug 1335492

The log file from comment #67 indicates that the icon order can still partially reset with the latest version.

During session start the size of the desktop area may change several times (mainly due to panels being started slowly). However, only the final size is appended to the name of the save file later on.
So, xfdesktop iterates through the desktop files/icons to restore their positions. It tries to find the according save file for the _current_ (maybe temporary) size of the desktop area. This fails for the first few icons, because only a save file for the final size exists.

Sadly, I was not able to work on this yet. It needs to be discussed with Eric also.
