Thank you for taking the time to report this bug. We have tried to recreate this on the latest release of Ubuntu and cannot reproduce it. This bug is being marked as Invalid. If you believe the problem to still exist in the latest version of Ubuntu please comment on why that is the case and change the bug status to NEW

This bug affects me also. I typically have 10+ tabs open in Chrome. If I drag an item within chrome (often done by accident) the chrome window usually goes white with no tabs, URL line or bookmarks showing. The mouse still moves but I cannot click on anything or alt-tab to another application.
If I switch to a console such as ctrl-alt-F1 I can log in and running top shows nothing unusual such as chrome using more cpu/memory than it usually does. Killing chrome from the console does not restore the GUI, ctrl-alt-F7 remains as it was with chrome window all white and an unresponsive Unity toolbar. If I run Unity it resets and I can continue.

The only entries in syslog about the time of the hang are:
Apr 9 16:13:45 marty-ThinkPad-T420 console-kit-daemon[3356]: (process:24825): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

and dmesg:

Although this has happened to me a number of times I have not been able to reproduce it by trying to drag things in chrome. The last time it happened I was trying to select some text to copy but clicking and moving the mouse 'grabbed' something on the page rather than selecting the text. At least it seemed that way but note that the page I was on typically opens a popup if I perform any actions such as clicking on the page. I block this using the add on Javascript PopUp Blocker. So wondering if that add on is causing the issue?
