Description Milan Bouchet-Valat 2010-12-01 07:47:23 UTC

I wanted to debug telepathy-idle because of a crash (bug 29103), but it aborts as soon as I start Empathy. So I can't go further to catch memory errors...

I'm using version 5.5.4, telepathy-idle 0.1.6 on Ubuntu 10.10.

Comment 1 Simon McVittie 2010-12-01 08:44:41 UTC

(There is no telepathy-idle 5.x - presumably you meant telepathy-mission-control, and this isn't an MC bug.)

Thanks, this stack trace is hopefully enough to find the bug.

I could not reproduce this. Is this prblem still present in the latest Telepathy Idle code in Git?

Comment 3 Will Thompson 2012-11-14 18:11:37 UTC

Given that Debarshi replaced Idle's home-grown network code (in which this crash occurs) with using GIO, and neither of us can reproduce this crash, I'm going to take the liberty of resolving this bug.
