So, finally did the import contacts bug was fixed?.
To make it clear. in the phonebook app, if you uncheck google contacts, and choose to list only contacts with phone numbers, you will end with an empty contact list, and that is normal. BUT, if you import a vcf file with your own contacts (not from google ones), you will see your vcf file on your contact list. The bug is that after importing that vcf file, the list remains EMPTY.
I suspect that this issue is caused by mixed apk's regarding to an one phonebook. This is the only GB, ICS, JB rom that has this issue.
