Description Mardy 2012-09-05 08:01:36 UTC

Testing empathy with UOA, libfolks 0.7.3. This bug happened when re-enabling the google account right after disabling it. BTW, the contact list was not cleared from google-talk contacts when the account was disabled, but I'm going to report that issue separately (against Empathy).

I don’t think so.

I can’t figure out the cause of the crash from this. It looks like a refcounting issue (previously-finalised PersonaStore getting used again) but it could be anywhere.

Mardy, if you can reproduce the crash, can you get the following output from gdb please?
    frame 0
    print *self
    frame 1
    print *[whatever the variable name is for the persona]
    print *[as above]->priv
    call folks_debug_emit_print_status(folks_debug_dup())

The variable name for the persona can be found on line 6708 of individual.c. I don’t know what it is because my line numbers are different.

Also, it would be useful if you could do all this with the following environment variables set: FOLKS_DEBUG=all G_MESSAGES_DEBUG=all. The output could then either be attached here or e-mailed to me privately (if it contains personal information).

Thanks.
