Bug Description

Apport-retrace process uses over a gigabyte of memory for retracing a bug with ~20Mb compressed core dump. I'm not sure if it's a bug (memory leak?), but it does make my system swap to disk, which completely blocks any other tasks.

I've experienced it on bugs in https://launchpad.net/geary and https://launchpad.net/midori; example bugs that cause this behavior are bug 1086007 and bug 1085962. Unfortunately I can't make them public, but I can subscribe people to them. I'll keep my eyes open for such bugs without private info.

I use a trunk checkout at revision 2537. The exact apport-retrace invocation I use is this:

PYTHONPATH=. bin/apport-retrace --stdout --auth=~/.cache/apport/launchpad.credentials --sandbox=/home/serioga/Code/apport-retrace-sandbox/ <bug-number-here>

The sandbox in use can be viewed at lp:~elementary-os/elementaryos/apport-retrace-sandbox

For bug 1085962 when using cache apport-retrace process goes up to 1,5Gb before the distro release folder is created in the cache directory. It uses at about 800Mb of memory while downloading packages.
