stacktrace clear of private data, making public

[Brian Curtis (bcurtiswx)]

Sent upstream. Marking as triaged.

Crashed on me, simply trying to launch the program

[Guillaume Desmottes (cassidy)]

This trace is no the same as the one of https://bugzilla.gnome.org/show_bug.cgi?id=579983

[Guillaume Desmottes (cassidy)]

Possible fix in http://git.collabora.co.uk/?p=user/cassidy/empathy;a=shortlog;h=refs/heads/fix-lp-392678
Waiting for review.

[Brian Curtis (bcurtiswx)]

Guillaume,

Thanks, I will wait for the review before changing things around in the case it's a fix I can just mark appropriately.

[Guillaume Desmottes (cassidy)]

Fix has just been merged to master. Will be in 2.28.0.

    dispatcher_request_failed: check if conn_data is not NULL

    Trace attached on lp #392678 seems to indicate that the
    priv->connections hash table doesn't have a ConnectionData associated
    with the connection. A possible explanation could be that this
    connection has been invalidated before the RequestChannel call is
    terminated.

    Check if ConnectionData so Empathy won't crash in such case.

Closing the bug the new version is in karmic now

[Rudolf Meijering (skaapgif)]

I have Karmic with the latest updates, but empathy still crashed when I tried to join a room.
