I am having a similar problem with QGIS Master on Ubuntu 14.04 64 bit. 
Since about a week ago I get the following error message:
Warning: loading of qgis translation failed 
[/usr/share/qgis/i18n//qgis_en_GB]
Warning: loading of qt translation failed 
[/usr/share/qt4/translations/qt_en_GB]
Warning: QGraphicsScene::addItem: item has already been added to this scene
QGIS died on signal 11Could not attach to process.  If your uid matches 
the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
No thread selected
No stack.
gdb returned 0
Aborted (core dumped)

I've also uninstalled and reinstalled QGIS but it still crashes on 
startup. I've also tried running QGIS with the --noplugins switch but 
this hasn't helped, nor does running it with sudo.

I wonder whether there has been a recent Ubuntu update that is causing a 
problem on some machines?
