I thought that was fixed, will check that later. Not sure if it's a good 
idea sharing /home with other OS but that's up to the user.

I know.. will fix in next version. In the meantime, in 
~/.trinity/share/config/startupconfig 
change:(kpersonalizerrc_general_firstlogin=)"true" to "false"

Difficult to help with that because here, iceweasel works normally 
post-install but will check again.

Can't help much with skype except you seem to have installed from a 
"stable" repo while this is Jessie (testing), whether that version is 
suitable for Jessie I don't know.
