Bug#391287: hangs for couple minutes on login and logout

[Jack Bates]

Package: gnome-session
Version: 2.14.3-1

I recently started using gnome-session, but logging in and out now take
a couple minutes. When logging in, for instance, the esd chime plays,
the gnome-session start widget appears and the window manager icon
appears in it. The interface then hangs for a couple minutes before any
other icons are displayed in the start widget.

At the same time, these lines appear in .xsession-errors:

Gnome-Message: gnome_execute_async_with_env_fds: returning -1 
Gnome-Message: gnome_execute_async_with_env_fds: returning -1

I tried using strace to diagnose the problem. Login hangs at 11:48 and
logout at 11:51. 11:48 corressponds in strace.4227 to theses lines,
repeated over and over:

11:48:21 gettimeofday({1160074101, 114823}, NULL) = 0
11:48:21 ioctl(3, FIONREAD, [0])        = 0
11:48:21 gettimeofday({1160074101, 115020}, NULL) = 0
11:48:21 poll([{fd=37, events=POLLIN}, {fd=18, events=POLLIN}, {fd=3, events=POL
LIN}, {fd=29, events=POLLIN|POLLPRI}, {fd=33, events=POLLIN|POLLPRI}, {fd=34, ev
ents=POLLIN|POLLPRI}, {fd=35, events=POLLIN|POLLPRI}, {fd=36, events=POLLIN}, {f
d=43, events=POLLIN|POLLPRI}, {fd=42, events=POLLIN|POLLPRI}, {fd=26, events=POL
LIN|POLLPRI}], 11, 124) = 0

I think process 4227 is originally started in strace:

11:47:53 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGC
HLD, child_tidptr=0x30036728) = 4224

It's not clear to me what gnome-session is doing while it hangs. I'm
not sure what to do next to diagnose this problem.

Thanks, Jack
