My guess is that Qt calls setlocale (LC_ALL, "") or similarly and you are using
UTF-8 locale or something similar.
ISO C99 requires for %.*s to only write complete characters that fit below the
precision number of bytes.  If you are using say UTF-8 locale, but ISO-8859-1
characters as shown in the input file you provided, some of the strings are
not valid UTF-8 strings, therefore sprintf fails with -1 because of the
encoding error.
That's not a bug in glibc.
