For the ptrace problem, it could be related to that:

https://wiki.ubuntu.com/SecurityTeam/Roadmap/KernelHardening#ptrace%20Protection

and indeed:

ypig:~> cat /proc/sys/kernel/yama/ptrace_scope
1

Setting it to 0 is obviously not the right thing to do. The solution
must be implemented in gdb (e.g. by being suid root and dropping
permissions when possible... or something else...).

Running iceweasel from gdb may be a workaround, but this may be too
late (e.g. to get a backtrace of some frozen process).
