I have the same issue with mouseovers crashing CEF. I can reproduce the issue on Ubuntu 12.04 32-bit using cef_binary_3.1547.1551_linux32_client (version used by cefpython-29.2) as well as with cef_binary_3.1720.1548_linux32_client (current trunk).
However, I have no problems at all on my dev environment of Ubuntu 13.10 64-bit.
$ DISPLAY=:0 ./cefclient --off-screen-rendering-enabled --url=http://tests/other_tests
[0108/144904:INFO:gpu_info_collector_x11.cc(80)] NVCtrl extension does not exist.
The program 'cefclient' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 735 error_code 2 request_code 94 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Any link whatsoever causes it to crash, even the links on the built-in tests page. In my application, I am working around this issue by not passing any mouse move messages to CEF - it no longer crashes. Also, this seems to happen solely in offscreen rendering mode. Without '--off-screen-rendering-enabled' cefclient does not crash - however, my application uses Kivy and cefpython, and must use offscreen rendering.
