# ABRT Bugzilla Duplication Checker
# Downloads all backtraces reported by ABRT from Bugzilla,
# and search for duplicates using the newest ABRT duplication
# checker.
#
# Some bugs in Bugzilla were reported by older ABRT
# versions, which had poor duplication detection.
#
# Please do not run this script unless it's neccessary to do so.
# It forces Bugzilla to send data related to thousands of bug reports.

#
# Useful text to be pasted to Bugzilla:
"""
This bug appears to have been filled using a buggy version of ABRT, because
it contains unusable backtrace. Sorry for the inconvenience.
Closing as INSUFFICIENT_DATA.
