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:
