latest chromium-browser using high cpu on any page

[sd]

Hi,

since last update of chromium-browser on Lubuntu 13.10 the CPU usage is 
very high with any open page:

Version 31.0.1650.63 Ubuntu 13.10 (31.0.1650.63-0ubuntu0.13.10.1~20131204.1)

Task Manager (lxde)

Command User CPU% RSS VM-Size
chro root 27% 222.0 MB 1.3 GB
chromium-browser user 11% 72.1MB 16777216.0 TB

It just goes higher and higher if you open any more pages, until the 
system does not respond anymore.

I know chromium-browser is not the default browser anymore, and I am not 
sure where to report this issue. Firefox is running ok, so I am 
switching to it atm.

Regards, p
