mserver5: gdk_bat.c:1015: setcolprops: Assertion `x != ((void *)0) || col->type == 0' failed.

When trying to import a reasonably big dataset, I end up with the above error after the copy statement. The incident can be reproduced by loading the specific file.

Statement used:
copy 7624307 records into "sys"."xxx_2015_04" from '/mnt/storage1/tmp/xxx_2015_04.csv.gz' delimiters ';', '\n' null as '';

detect incorrect input earlier (ie preventing out of buffer writes)
