Loading a db_text file with one unterminated line causes crash #308
Description
If a database file only contains one line with the column type definitions, it is only parsed correctly (as an empty table) if the file ends with a newline. If not, loading the file crashes opensips.
I looked at a gdb backtrace, but not investigated it any further.
Program terminated with signal 11, Segmentation fault.

Using version 1.11.
As a related issue: if a table has records, but the last record's line is unterminated, that record is silently ignored.
