Bug#715667: [Mayhem] Bug report on dvb-apps: azap crashes with exit status 139

Hello,
azap crashes because of a strlen(0) because homedir/$HOME is not set.

Minimal statement to reproduce:
	$ env -i azap 1

Following patch exits immediately after the
message, therefore avoids the crash.

Kind regards,
Bernhard
