This patch resets the anchor properly after resetting cursor at load time.
Candidate to master and 2.1 branch.
Thanks. Unfortunately I just had a similar assertion in a condition
unrelated to what this patch fixes:

I was selecting text and this was not a document that I had just opened
nor did I just use a bookmark, so as I understand the patch would not
have prevented the above. (From now on I will work on the latest master
with the fix, to be sure.)
I also wanted to say that I am trying to catch a dataloss crash in
master, where a blank emergency file is produced. I do not know if it is
related to the issue above, but it is why I am currently working with
gdb. This dataloss crash is unrelated to math macros, because there were
no macros in the document at the time.
