Error is specific to dash. Script works fine with bash shell.
Workaround: Upgrade bugzilla. Upgrade will fail. Edit "/usr/share/bugzilla3/lib/checksetup.pl" and change shebang line (#!/bin/sh) to #!/bin/bash.
Since dash is the default shell now, this script should either use bash or should work with dash.
