Chrominum Locks Up Ubuntu 14.04

[Lonnie Lee Best]

Twice today, I had to shutdown my Ubuntu 14.04 improperly due to system lock-up.

Each time the lockup happened, these are the exact steps I did:
1) Launch Chromium browser
2) Go to https://login.microsoftonline.com
3) type in an email address
4) Press tab (attempting to move cursor to password field)

At this point the entire system locked up.

The only recent package I recall installing (related to Chromium) was the pepperflashplugin-nonfree. So, it may be a bug in that plugin that is the culprit. I'm not sure, but I hope my report helps.

When I installed chromium, I did so with two other packages:

sudo apt-get install chromium-browser chromium-codecs-ffmpeg-extra pepperflashplugin-nonfree

Hope that helps.

It may be a coincidence that Ubuntu 14.04 locked up the two times I repeated the steps outlined in this report.

I now recall an old bug I reported that might be the true cause of this issue:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1314368

I'm not certain, but again, I'm reporting all I know.

Lonnie,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu and Chromium since that time.

We would like to close this bug report but before we do we are asking do you still see a problem related to the one that you reported? Please let us know if you do.

If we do not hear from you the bug report will close itself in approximately 60 days time.

Thank you for helping make Ubuntu better.

No reply to comment #4 so closing as bug task did not expire

Sorry, just now seeing this. I just want to confirm that I don't have the issue anymore.
