Trying to report xorg bug, apport balloons to >1GB of memory and uses 20GB of disk before crashing

I get an xorg crash (due to fglrx) regularly, but any time I try to report it, apport takes a long while ballooning up to over 1GB of RSS and uses disk space until it runs out of it (c. 20GB of my 50GB root fs).

The crashing bug is apparently being fixed in bug 1168849, so this is only for the memory and disk use.
