Segfault at starting (probable cause :libindicate patch ) on kde

[Laurent Claessens]

I'm forwarding a bug from upstream.
https://bugzilla.gnome.org/show_bug.cgi?id=595980

Empathy has a segfault when starting. Here is the backtrace from gdb:

As far as I tested bug impactes the version 2.28.0, but not the 2.27.* branch.

Remark 1 : this bug could be KDE-specific in the sense that I don't have the crash when I start Empathy in Gnome.
Remark 2 : when I launch Empathy in Valgrind, I don't have the problem. I attach the log of Valgrind (but it does not contains the segfault)

[Laurent Claessens (moky-math)]

I have to correct one statement : the Valgrind's log contains in fact some segfault. A friend who knows about read it and said me that the lines with "Invalid write of size 4" and "Invalid read of size 4" indicate the segfault. However, Empathy did not crashed during the Valgrind cession.

All my friends but me are developpers:)

and your brother too :p

I think you should also say that this segfault happens on kde

[Xavier Claessens (zdra)]

reported said that this bug can't be reproduced now.
