This bug was fixed in the package apport - 2.0.1-0ubuntu6
---------------
apport (2.0.1-0ubuntu6) precise-proposed; urgency=low
* Cherry-pick from trunk:
- hookutils.py, recent_logfile(): Use a default limit of 10000 lines and
call "tail" instead of reading the whole file. This protects against
using up all memory when there are massive repeated log messages.
(LP: #984256)
- apport-gtk: Do not assume that an icon requested for size 42 actually
delivers size 42; some themes do not have this available and deliver a
smaller one instead, causing overflows. Also, copy the image as
gtk_icon_theme_load_icon() returns a readonly result which we must not
modify. Fixes crashes when using themes other than the standard Ubuntu
ones. (LP: #937249)

Title:
recent_logfile() causes a huge memory leak for large log files

Fix Committed
Status in “apport” source package in Precise:
Fix Released
Bug description:
SRU TEST CASE: See comment 7
At some point, an apparent memory leak has been introduced into apport
making it bring systems to a grinding halt while it tries to run.
I've noticed this over the last few days, so I suspect it's a fairly
recent change. Today, I've tried filing a bug twice using apport,
however, each time, the apport process chews through up to 3.5GB of
RAM before it finally crashes. Here's the python trace generated
after it finally runs out of memory:
