            Bug ID: 331289
           Summary: Buggy reading of dirfile's BITFIELDS channels coming
                    from gzipped raw channels
    Classification: Unclassified
           Product: kst
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: datasources

I write a compressed dirfile using the gzip compression of getdata.
This dirfile has an int8 raw channel, 'flag_raw',  and from this raw channel I
make a 1 bit long derived bitfield channel called 'flag0'
KST the reads the raw channel 'flag_raw' ok, but reads the 'flag0' wrong. I've
seen it either show no datapoints, or show all zeros.


Reproducible: Always




The gzipped compressed data was written using pygetdata. I checked, and
pygetdata can read the gzipped bitfields properly.
