Debug info from gdb:

Could 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 threads.

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

Aborted (core dumped)

This means that somehow your 3.0 mono is using a 2.10 mscorlib.dll, or vice
Comment 2 Zoltan Varga 2013-01-02 08:53:27 EST
The assertion is now fixed in master, a normal error message is now displayed
for these cases.
