Multiple Web Apps crashes when returning from a linked page

I've been noticing this on Krillin since a few weeks (now I'm on rc-proposed/bq-aquaris.en r388), I had not noticed it before, so maybe it got worse than it was before?

Is there an update about this bug @Alex ?

"free -h" output on my Krillin while running a webapp, crash included

http://pastebin.ubuntu.com/20158255/

I'd like to add some details:
I have not noticed this issue in the past 1year 5months of using Krilling as my daily driver, until a month or so ago.

I believe the system memory usage increased over time to the point of making this bug much more evident since a few weeks (a month? maybe even 2? I'm not sure).

It would be good to give this another push, if possible :)

can we reprioritize it?

Poke. Can we please land the proposed fix? It's one of the most annoying Touch bugs right now for me.

Yes, please fix this, all webapps are broken due to this bug...

I agree it's incredibly annoying. Can we get an update on this? :)

Suppose you enter the app "My Web Apps" and choose a place. If there is a link to another place and you enter it, when you return to the previous place pushing a button down left, perhaps you return or perhaps the program breaks.

This bug also affects the desktop webapps, e.g. Google+ and Twitter.
Is there a fix too?

Cheers,
Laryllan
