Thanks to @alarixnia fot the patch and bugreport.

Forwarding a bug reported using the NetBSD bug tracker ("Profanity crashes at login"): http://gnats.netbsd.org/57050
The code in question here handles messages by people not in the user's contact list, and what is probably happening is that the XMPP server is sending such a message before profanity has set up its window layout.
Setting roster.unsubscribed=false indeed makes profanity start without crashing, and the attached patch bails out early in the problematic code path if layout->subwin is NULL (Adrian verified for me that either of the two makes profanity work for him again). But I am not familiar enough with the profanity code to say if this has any issues.
Profanity compiled with ncurses doesn't crash because ncurses's wattron() has a guard against the user passing null pointers, but the X/Open curses library standard doesn't have this guarantee and there's no guard in the NetBSD curses implementation.

Fix https://github.com/profanity-im/profanity/issues/1769
This commit fixes few issues related to OMEMO autodetection:
1. Absence of libsignal-protocol-c doesn't turn OMEMO off, just prints a
notice message. It should (a) set BUILD_OMEMO=false and (b) terminate
with an error on --enable-omemo=yes.
2. Check for gcrypt continues even if libsignal-protocol-c fails. In this
case, LIBS variable can be updated with unneeded -lgcrypt.
3. Similarly to item 2., if libsignal-protocol-c is present, but gcrypt
isn't, variable LIBS is updated with unneeded library.
To resolve the above issues, use intermediate variable OMEMO_LIBS to
accumulate required libraries and set BUILD_OMEMO only when all checks
are passed.
Add ability to completely turn logs off,
Needed since `/logging` and `/history` didn't stop history logging
in the DB, only in files.
Command might break something on usage,
hence it was primarily introduced for privacy geeks.
Privacy command discussion #1836
Refactor `p_gpg_list_keys`
Add `/pgp autoimport` command,
it's not described in XEP-0027, but used in some clients,
such as PSI, Pidgin. It will autoimport keys received with
`/pgp sendpub`, in plain text as a message, or using features,
provided in other clients. It doesn't autoassign them, but shows
command to assign, letting user to decide.
Improve documentation for some preexisting functions
Add contact argument to `/pgp sendpub`
Improve documentation
Update code formatting and indentation for better readability
Show state if no argument provided
Show if argument wasn't changed
Reduce amount of arguments
Command allows to share your PGP pub key with ease,
it's not described in XEP-0027, but used in some clients,
such as PSI, Pidgin.
