Users home directory wiped after dist-uprgade

[Wackojacko <wackojacko32@ntlworld.com>]

I am running an up-to date sid system on amd64. Self compiled kernel 
2.6.14.  Following the kde upgrade today my /home/user/ directory was 
deleted.  Luckily I had a backup from this morning so nothing major was 
lost, but anyone had any similar experiences or could offer up a 
possible explanation?

Thanks in advance
