The bug is caused by libxmlrpc-lite-perl and libsoap-lite-perl
libsoap-lite-perl depends libxmlrpc-lite-perl, while the latter one recommends the previous one.
The step to reproduce:
1.Install libsoap-lite-perl, make sure libxmlrpc-lite-perl is marked as auto-installed
2.Select package libsoap-lite-perl, Press 'M'
3.Press 'g'
4.Select libxmlrpc-lite-perl or libsoap-lite-perl, press '_'
