Bug 469724 – net-irc/telepathy-idle-0.1.16 consumes too much CPU time

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description qdii 2013-05-13 19:24:15 UTC]

I run on an unstable wifi connection, this happens every time when my wifi disconnects then reconnects. My solution is to kill telepathy-idle.

I attached gdb to it:

You will need to rebuild packages providing /usr/lib64/libglib-2.0.so.0 and /usr/lib64/libtelepathy-glib.so.0 with debugging symbols to get useful traces:

Please also check in .15 and .14 versions to be sure it's a recent regression or not

Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=64923
It's fixed in 0.1.17 and streightforward bump of net-libs/telepathy-glib to 0.21.2 and net-irc/telepathy-idle to 0.1.17 at least built fine.
