apport-retrace with -g leaves core files

I've been using apport-retrace with the -g argument to launch gdb and test some stuff and I realized my disk was getting full. Lo and behold:

[ 1:54PM 10208 ] [ bdmurray@impulse:/tmp ]
 $ ls -lh apport_core*
-rw------- 1 bdmurray bdmurray 866M May 19 12:11 apport_core_1ati4pjm
-rw------- 1 bdmurray bdmurray 52M May 17 12:02 apport_core_6mptlmfq

I'm guessing if you use apport-retrace with -g the core file gets left behind. It'd be nice if you didn't have manually clean up after apport.
