[Bug 1472755] Re: /usr/lib/arm-linux-gnueabihf/unity-scopes/scoperunner:*** Error in `/usr/lib/arm-linux-gnueabihf/unity-scopes/scoperunner': corrupted double-linked list: ADDR ***

 

I believe I may have found the source of the problem. When the scope is aggregated, the author assumed they can access results[0], which may not be true if:
1) the user is signed in
2) but has no messages whatsoever

That'd mean the scope would crash for all users, who have set up
Telegram account, but not really used it.

Michi, if you have time, perhaps you could verify my finding. In the
mean time, I'm rewriting the scope source as the backing database schema
has changed (after we moved to making use of TelegramQML plugin).

** Changed in: libqtelegram (Ubuntu)
