gnome-session: drop bashism from shell script (1.12 KB, patch)

Description bluescreen_avenger 2016-08-25 01:47:48 UTC 
I only found Bug#835289 reported against Debian itself as the only recent result

It seems it was caused by 4abdb7925c3bf91e0802e42bab6c90d9a3086b2e
Another result in Google from 2008 is that this error can happen in the dash shell which Ubuntu (and I guess debian as well) uses in replacement for sh
Comment 1 bluescreen_avenger 2016-08-25 02:05:18 UTC 
forgot to mention, changing the shell to bash allows the gnome-session to run normally
Comment 2 bluescreen_avenger 2016-08-25 02:09:52 UTC 
Might need to change the line to 
dbus-update-activation-environment --all /dev/null 2>/dev/null ||:

gnome-session: drop bashism from shell script

Apparently dash doesn't support >& and some people use dash.

This commit changes it to the more wordy form > ... 2>&1 .
