ABRT duplicate detection - is it for real?

[Christoph Wickert]

I'm getting the same bug reports over and over again, for example
https://bugzilla.redhat.com/show_bug.cgi?id=542393

Shouldn't ABRT catch the duplicates?

AFAIK abrt recognizes dupes based on hashes of the backtrace, but the
format of the backtraces has changed with nearly every new ABRT version,
so the backtraces will not be the same even from exactly the same crash.

How to deal with that problem? And what about more complicated cases,
for example a backtrace where the commandline is different  as
in /usr/bin/program /home/user/some.file. As user and filename change,
the hash cannot be the same.
