Hi,
I'm running IDB 13.0 in Ubuntu 12.10 and I found that if I start my code from the debugger I can open the source code without any troubles, but if I start the code (which waits in a loop) and then attach to it from inside the debugger, then I cannot see the list of the source files.
I open the code and the debugger from the same directory, so finding the files should not be a problem, but I don't know what could be happening. I include screenshots in case they can be of interest.
Any suggestions?
Thanks,
Ángel de Vicente

Hello,
sorry for the delay, our notifications were down. I can confirm this problem for Ubuntu 12.04. Older Ubuntu versions seem to work well. I've escalated this problem to debugger engineering (DPD200240305). As soon as I hear back from them I'll let you know.
Best regards,
Georg Zitzlsberger

Hello,
the solution is to set /proc/sys/kernel/yama/ptrace_scope to 0.
Please be aware about potential security implications. See more information here:
