[ubuntu-mono] [Bug 769545] [NEW] banshee closes two seconds after opening

[Chow Loong Jin]

Could you try running:

sudo sysctl kernel.yama.ptrace_scope=0
banshee --debug

And then posting the output here? It looks like there's a separate bug in mono
that does not handle gdb attaching properly, so this is a workaround to get a
proper backtrace.

To be safe, you could set the value back to 1 after you have gotten the output:
sudo sysctl kernel.yama.ptrace_scope=1.


  status incomplete

Title:
  banshee closes two seconds after opening

Status in “banshee” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: banshee

  Every time I start banshee it closes two seconds or so after opening.
  I have tried with and without plugins.

  This message is displayed if started from a terminal window:

  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.
