While testing Qt 5 support on Ubuntu, and validating the support for OpenGL ES2.0 with Pandaboard, I couldn't start Snowshoe (Qt 5 - webkit based browser) as it gives a segmentation fault and also breaks the X11 server (with the pvr driver).
After a quick check with Snowball (Mali 400), it worked properly and as expected, so this could probably be related with the current SGX driver available for Pandaboard.
How to reproduce the issue:
1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily
2) Install 'snowshoe-mobile' package
3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe
This is with Ubuntu 12.04 with pvr-omap4 1.7.10.0.1.21-0ubuntu1 (from archive) and also 1.7.15.0.1.57-1 from TI's PPA. |

[Impact]
Segmentation fault at X11 where the randr code could use the randr screen private data without checking for null first. This happens when the X server is running with multiple screens, some of which are randr enabled and some of which are not. Applications making protocol requests to the non-randr screens can cause segfaults where the server touches the unset private structure.
This happened initially while running Precise on a Pandaboard, as with the driver auto-load, it starts 2 different screens, one backed up by the PVR SGX driver, and the other by fbdev. In this case, the issue can easily be reproduced by running any QT5 based application, as by default it'll try to initialize the internal structures for all screens available at the system.
The bug can also happen on cases where the user is running one screen with the nvidia/ati driver, and the other with fbdev (external usb video device, for example).
[Test Case]
How to reproduce the issue, on a Pandaboard:
1) Install Precise at a Pandaboard;
2) Enable the PVR SGX driver from the "Additional Driver" screen;
1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily
2) Install 'snowshoe-mobile' package
3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe
Broken Behavior: X11 will exit with a seg fault
Fixed Behavior: The QT5 based application (snowshoe) will open without crashing X11.
[Regression Potential]
Both patches are already applied at upstream, and they are simply just checking the pointers for NULL results, which would already cause a seg fault in case of NULL value, so it's safe to be applied as SRU.
