This bug also occurs if the parent folder is a top level folder.
Additionally the bug occurs if you enter the folder tree view on the 
height of a collapsed folder while dragging a message.

I inserted some kdDebug's in KMFolderTree::contentsDragEnterEvent
and in KMFolderTree::openFolder and found out that the autoopen_timer 
is started when you enter the folder tree view but openFolder is only 
called if you drag the message above another folder than that where you 
entered the folder tree view.

This is really strange. Unfortunately I don't know enough about signals 
and slots to solve this mistery.

BTW, I you drag the mouse pointer very slowly over the last folder in 
the folder tree view and stop the mouse just after the last folder is 
selected then the last folder will also expand automagically. But if 
you drag the mouse pointer to far down the folder won't expand. I 
suspect this is due to some conflict between the automatic expanding of 
folders and the automatic scrolling of the folder tree view.

Regards,
Ingo
