Comment 1 David Edmundson 2013-07-03 15:56:50 UTC 
Confirmed.

To save someone else looking, crash is in getting the contact ID in AccountRole when contact is null.

Added kpeople flag which I want set for all _kpeople only_ bugs.
Comment 2 David Edmundson 2013-09-01 14:29:39 UTC 
I have not seen this crash in a while (only the QStandardItem::emitDataChanged (this=0x1de7670) at itemviews/qstandarditemmodel.cpp:867) crash.

Anyone else?

Same here. But this renders ktp-c-l almost useless. After first successful showing of list, every succeeding try results in a crash...
If you have the same as:

Comment 4 David Edmundson 2013-09-01 17:53:05 UTC 
Follow that here: https://bugs.kde.org/show_bug.cgi?id=322134

Note that it is marked for 0.7 milestone, if it still exists when it comes to the release.. we don't release. (or I pull the kpeople support completely)

As for that bug, I /think/ I have a fix.

CC'ed already ;-)

Ah,  great :-)
