Why is this being denied on a file with these permissions? |
Which "user" issue the nc command? is it 134? I think the /run/user/134 directory does not allow other go in there for read/write. |

I guess because of the permissions of /run/user/134.
What is the value of $XDG_RUNTIME_DIR? |

OK, thanks both...its true /run/user/134 is rwx------ so stricter than the file itself.
And
| Code: | # echo $XDG_RUNTIME_DIR
/run/user/1000 |
(which is me, 1000, the user)

Your XDG_RUNTIME_DIR looks correct.
Does the at-spi bus exist for your user?
| Code: | | ls -l $XDG_RUNTIME_DIR/at-spi |
? |

No, it doesn't:
| Code: | # ls -l $XDG_RUNTIME_DIR/at-spi
ls: cannot access '/run/user/1000/at-spi': No such file or directory |

Does it exist after executing (as normal user) | Code: | | /usr/libexec/at-spi-bus-launcher --launch-immediately |
? |

Apologies for the delay...
| Quote: | | Does it exist after executing (as normal user) |
No it doesn't
| Code: | $ /usr/libexec/at-spi-bus-launcher --launch-immediately
$ ls -l $XDG_RUNTIME_DIR/at-spi
ls: cannot access '/run/user/1000/at-spi': No such file or directory |
And thanks for your help...

look at permissions for directories above.
/run/user/137 and /run/user/134/at-spi i think they have 700 permisions.

Yes that's right (see about 6 comments back rwx------ =700).
I have set an environment variable NO_AT_BRIDGE=1. This stops the xsession errors. It may possibly solve the problem of evolution not working too, but I have uninstalled evolution, so can't check. But this seems more like a workaround than a solution.

| I would expect that the /run/user/uid directories should be mode 700. The question then is why these programs are trying to poke around in run directories other than their own. This is probably due to an incorrect environment variable instructing them to look there. |
