Comment 1 Tim Waugh 2008-05-22 10:03:56 UTC
I haven't been able to reproduce this problem.

Please enable cupsd debugging like this:

  service cups restartlog
  cupsctl --debug-logging

and try again.  When cupsd segfaults again, please attach the
/var/log/cups/error_log file to this bug report.  Thanks.

copy_banner is being called with the first parameter as NULL, copy_banner does
not check for this.
