When I wrote the bug report, I wasn't thinking of bugs internal to
getdata; I was thinking of when people write their own format files
which contain typos/invalid entries.  We've been seeing alot of these
since we started data analysis on BLAST and people are creating their
own raw data and adding (by hand) entries in the format file.  If these
entries are mistyped or invalid or missing (both the binary data missing
or the format entry missing) kst silently fails.
