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: Thread 3: #0 0x00007f124ba67095 in pthread_mutex_lock () from /lib64/libpthread.so.0 #1 0x00007f124c13aab1 in g_mutex_lock () from /usr/lib64/libglib-2.0.so.0 #2 0x00007f124c0fad23 in g_main_context_release () from /usr/lib64/libglib-2.0.so.0 #3 0x00007f124c0fba18 in g_main_context_iterate.isra.22 () from /usr/lib64/libglib-2.0.so.0 #4 0x00007f124c0fbf4a in g_main_loop_run () from /usr/lib64/libglib-2.0.so.0 #5 0x00007f124bddd8d2 in tp_run_connection_manager () from /usr/lib64/libtelepathy-glib.so.0 #6 0x000000000040ab96 in main () Thread 2: #0 0x00007f124c13aad9 in g_mutex_unlock () from /usr/lib64/libglib-2.0.so.0 #1 0x00007f124c0fb183 in g_main_context_prepare () from /usr/lib64/libglib-2.0.so.0 #2 0x00007f124c0fb98e in g_main_context_iterate.isra.22 () from /usr/lib64/libglib-2.0.so.0 #3 0x00007f124c0fbf4a in g_main_loop_run () from /usr/lib64/libglib-2.0.so.0 #4 0x00007f124bddd8d2 in tp_run_connection_manager () from /usr/lib64/libtelepathy-glib.so.0 Thread 1: #0 0x00007f124b79579d in poll () from /lib64/libc.so.6 #1 0x00007f124c0fba6c in g_main_context_iterate.isra.22 () from /usr/lib64/libglib-2.0.so.0 #2 0x00007f124c0fbb94 in g_main_context_iteration () from /usr/lib64/libglib-2.0.so.0 #3 0x00007f1249583b2d in dconf_gdbus_worker_thread () from /usr/lib64/gio/modules/libdconfsettings.so #4 0x00007f124c11f425 in g_thread_proxy () from /usr/lib64/libglib-2.0.so.0 #5 0x00007f124ba64f3b in start_thread () from /lib64/libpthread.so.0 #6 0x00007f124b79f4dd in clone () from /lib64/libc.so.6
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: http://www.gentoo.org/proj/en/qa/backtraces.xml 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.
