'Cannot execute /bin/sh' on opening new tab

[andreasf]

On creating a new tab in Terminal in hrev25161, an error message box appears, saying:

Cannot execute "/bin/sh":
  Bad address

It offers options to Abort or to Use Default Shell. For the latter, the Terminal reads

Use Default Shell

Welcome to the Haiku shell.

~>

echo $SHELL does return /bin/sh, and it exists.

Fixed in hrev25166.
