extensions: Ignore extensions in directories without read permission (1.24 KB, patch)
2011-03-02 13:45 UTC, Florian Müllner 		committed Details | Review

Description Richard Fuller 2011-03-02 13:29:15 UTC 
Version: 2.91.90

In my case:
/home/username/.local/share/gnome-shell/extensions - exists
/usr/share/gnome-shell/extensions - doesn't exist
/usr/local/share/gnome-shell/extensions - not statable, permission denied (due to Kerberised mount)

What should happen:
gnome-shell should start, using extensions in the paths it could read, and ignoring the path it did not have permission to read

What happens:
gnome-shell fails to start, error log...

extensions: Ignore extensions in directories without read permission

Gio.enumerate_children() throws an exception if called for a directory
without read permissions. Catch this case to allow the shell to start.
