Happened with the same action (downloading USNO catalog). Seems to be almost identical, probably the same problem. I think the backtrace is slightly more detailed.

I've installed Kstars on gnome desktop on Ubuntu 10.04.
Comment 3 Alexey Khudiakov 2010-06-28 20:44:09 UTC 
Thank you all for the detailed bug report. I think it's bug in KNewStuff or core libraries. USNO catalog had help to find such bug before
Comment 4 Alexey Khudiakov 2010-06-28 21:06:12 UTC 
I think it is really bug it the kdelibs so I'm reassigning the bug. Most likely it's 32-bit integer overflow. Unpacked USNO catalog is bigger than 2GB. 

Below is definition of function in which crash occurs. d->size has type qint64 while arr.size() has type int. So there is place to overflow. I maybe wrong but it's right direction to move.


QByteArray KArchiveFile::data() const
{
  archive()->device()->seek( d->pos );

  // Read content
  QByteArray arr;
  if ( d->size )
  {
    assert( arr.data() );
    arr = archive()->device()->read( d->size );
    Q_ASSERT( arr.size() == d->size );
  }
  return arr;
}


P.S. Reading whole file into memory isn't really good idea I believe.
