Dont know if pbap causes it...
but last night i ran a apt-get upgrade and everything went fine - but the obexd-installations...
upgrade said that no upgrade at this because of wrong version. not sooo bad.
But yet i wanted to go in the shell to get the older versions of obexd... i wanted: no more shell... no more menues except the screens... and no programm-manager any more... placed a shortcut to term on desktop - but it is not working...
as said above: i dont know IF pbap-workaround causes this... but be careful...
