Subject: [PATCH] Fix NULL pointer crashes from #175
|
||||
|
||||
avahi-daemon is crashing when running "ping .local".
|
||||
The crash is due to failing assertion from NULL pointer.
|
||||
Add missing NULL pointer checks to fix it.
|
||||
|
||||
Introduced in #175 - merge commit 8f75a045709a780c8cf92a6a21e9d35b593bdecd
