tracker-miner-fs crashed with SIGSEGV in g_type_check_instance_cast()

[Martin Constantino–Bodin]

Hi!
I don’t know why, but it seems that tracker-miner just Seg Fault.
As this bug seems new, I’m creating this new bug, but I don’t know anything about it (if it is reproducable or not…).
I hope there will be enough informations collected.

I’ve just found something strange in the tracker-status-icon: there is now a field “mail”, although I didn’t configure it and that this morning, there wasn’t (and I haven’t updated it since).
I have to say that Evolution crashes when launching indexation, maybe it’s linked.
That seems strange as I haven’t installed the plug-in in Evolution to handle it.

This bug thus seems strange… I hope apport collected enough information for it to be useful :)
Thanks!
Martin.

Just a little precision: I’ve just asked in the tracker-status-icon to stop indexations, then to unpause them and it seems to works.

This bug can thus be considered as a minor one.
