Comment 1 kde 2015-03-05 18:18:34 UTC 
It would be nice if the kcm would popup a message instead. I doesn't need to be explicit, but it is much better than a crash inside that kcm.
Comment 2 Malte Eggers 2015-03-08 12:10:50 UTC 
I can confirm this. Gentoo's solution for this is to simply require support for all the protocols to be installed, which is even more annoying.
Comment 3 kde 2015-03-09 01:44:57 UTC 
Yeah, there were two options:
1. USE flags and remove files of not selected services
2. just provide RDEPENDS for everything.

This bug is really annoying for packagers and users, because it pulls in a huge dependency tree including pidgin, even if you only want to use XMPP through KTP.
Comment 4 Martin Klapetek 2015-03-16 15:24:46 UTC 
I think I have a solution, not the best one as Apps 15.04 is in string freeze, but it will abort with error message.

Btw. how does it pull Pidgin? It should pull libpurple for telepathy-haze, but that shouldn't pull whole Pidgin...

[kaccounts] Don't crash on null profile

When the user selects an account for which an invalid Telepathy profile
exists, things should not crash but rather just warn the user.

As this plugin is now under string freeze, I've copied a string from the
old kcm (as it uses the same catalog), it's not ideal but this does not
violate string freeze and gives user at least a hint of what he should
do.
