Description Lukáš Karas 2016-02-19 12:05:01 UTC
Application: plasmashell (5.5.4)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.1 x86_64
Distribution: Ubuntu Xenial Xerus (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

When I loged in to my jabber account (telepathy-gabble), plasma notify my that someone wants to add me to his contact list. It was spam, so I decided block it. Then, plasmashell and ktp-contact-list crashed. It happens often and I have to block same accounts after each login.

I compiled KDE from source code just days before.

The crash can be reproduced sometimes.

I recompiled kpeople today and this bug still exists... 
kpeople head: a72809761419457b803e13ab91c1a1950b5f9ac8

I created simple patch that avoids `metacontacts[personRow]` access when `personRow` is < 0. 

diff --git a/src/personsmodel.cpp b/src/personsmodel.cpp
index 0c9fa13..13bdb50 100644
--- a/src/personsmodel.cpp
+++ b/src/personsmodel.cpp
@@ -343,6 +343,11 @@ void PersonsModelPrivate::onContactRemoved(const QString &contactUri)
 
     int personRow = personIndex[personUri].row();
 
+    if(personRow < 0){
+        qDebug() << "personRow: " << personRow << ", contactUri: " << contactUri << ", personUri: " << personUri;
+        removePerson(personUri);
+        return;

     MetaContact &mc = metacontacts[personRow];
     int contactPosition = mc.contactUris().indexOf(contactUri);
     q->beginRemoveRows(q->index(personRow, 0), contactPosition, contactPosition);

Console output when I remove spam contact:

personRow:  -1 , contactUri:  "ktp://gabble/jabber/ktp_2djabber_2dim_12?doofyntv6@swissjabber.org" , personUri:  "ktp://gabble/jabber/ktp_2djabber_2dim_12?doofyntv6@swissjabber.org"

It fixes these crashes but I don't know if this is correct place where it should be fixed...
