Hostname changes breaks application loading

[Joseph Reeves]

Binary package hint: hostname

On 9.10 changing the hostname via the terminal breaks the loading of applications until a reboot. You can see this below:

joseph@joseph-work:~$ nautilus

(nautilus:2068): Eel-CRITICAL **: eel_preferences_get_boolean: assertion `preferences_is_initialized ()' failed

[nautilus gives errors, but loads]

joseph@joseph-work:~$ sudo hostname example
sudo: unable to resolve host joseph-work

[change hostname to example, complains about my previous hostname]

joseph@joseph-work:~$ nautilus
No protocol specified
Could not parse arguments: Cannot open display:
joseph@joseph-work:~$

[Nautilus fails to open]

These are bugs in the individual applications, not the tool that changes the hostname

(and is probably because security authorisations tend to include the hostname)

[Sebastien Bacher (seb128)]

the issue would rather be in the xorg libraries used there

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

The bug is old and Ubuntu changed quite a lot since, there has also been no activity here nor similar reports. Closing since we believe the issue as described is deprecated but feel free to file a new report if you still have problems in recent Ubuntu versions.
