From 4db34f73d461b973867ddaf18bf690219229cd7a Mon Sep 17 00:00:00 2001

Subject: [PATCH] vncsession: use /bin/sh if the user shell is not set
An empty shell field in the password file is valid, although not common.
Use /bin/sh in this case, as documented in the passwd(5) man page, since
the vncserver script requires a non-empty SHELL environment variable.
Fixes issue #1786.
