No, the "issue" here may be different and intended: Isaac asked me to
build these packages with debug instead of release parameters, so you
are carrying the whole debugging slack.

You can try to rebuild the src.rpm with "--without debug" to see what
the performance penalty is from using debug flags. If there is a bug
difference then the "debug" packages make less sense and Isaac and the
other devs may concur to having trunk rpms with release like flags.

P.S. the trunk/bleeding discussions are probably better suited for
atrpms-devel, especially if you want to start doing custom rebuilds.
