I investigated this:
The problem is the strtok-function (IMHO):
A string like:
Test;1234;SM;1;5
results in the Tokens:
"Test", "1234", "SM", "1", "5"

but the string:
;;SM;1;5
results in:
"SM", "1", "5"
and not in the expected (at least by me ;-):
(null), (null), "SM", "1", "5"

So I have hacked gnokii.c to archieve this (see patch later on)
Now it deletes entries if the line ";;(mem);(loc);5" is the FIRST line 
of input for writephonebook.
This can be solved by moving the memset-call into the loop.

Now my patch:
moving the memset-call is IMHO a good thing (TM), but the rest is only 
a hack (and I think it won't be accepted into the CVS...) but maybe 
somebody else has an idea to solve it. (Maybe by not using strtok at 
all, quoting from man strtok: "BUGS: Never use these function....")

But here is my patch
