Sorry folks, I am new to this and will do my best.
I first reported this bug to Google. They got all the data here:
https://code.google.com/p/chromium/issues/detail?id=467821
and told me that this is a bug in the r600 driver.
Back in December I updated from 32 bit Ubuntu 12.04 to 64 bit Ubuntu 14.04 and
have had major stability issues with Chrome ever since, particularly while
using Google Maps.

was the first time I've managed to capture something that crashes chrome
reliably, however.
At their suggestion I tried running chrome with --disable-gpu and at least with
a simple test the problem went away.
I think these drivers are the default in Ubuntu now, but they seem to be
causing me a lot of grief.
You can pickup what Google got from the crash report Chrome sent to them from
the bug listed above.
And for the time being I will figure out how to run with --disable-gpu on all
the time to see if that avoids my issue.
Failing that I guess it's time to figure out how to go back to ATI's drivers.
If there is additional data I can provide somehow, I am happy to try. I'm no
wizard, but I will follow instructions and get whatever you need if possible.
Thanks.
