I opened a project that had a missing PostGIS layer. The dialog to fix the broken layer came up and immediately, QGIS crashed.
Warning: Loading a file that was saved with an older version of qgis (saved in 2.3.0-Master, loaded in 2.5.0-Master). Problems may occur. 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)
So I ran QGIS as root, I could fix the layer without crashing. Thereafter the project opened fine running QGIS as my user again.

Is there a particular reason why you think that running as root would have changed something?
The main reason I can think of is a configuration issue.
Can you try to move your .qgis2 folder to another location temporarily so you start with a clean configuration from scratch and then check if you still get a crash.
