Bug Description

I just upgraded my Nokia Booklet to Oneiric, and noticed that gnome-keyring-daemon is using about 40% CPU all the time.

Here's a snippet from strace:
time(NULL) = 1316942473
times({tms_utime=10433, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 940560}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 338520}, ru_stime={9, 72567}, ...}) = 0
time(NULL) = 1316942473
times({tms_utime=10433, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 941462}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 338520}, ru_stime={9, 72567}, ...}) = 0
time(NULL) = 1316942473
times({tms_utime=10433, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 942363}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 338520}, ru_stime={9, 72567}, ...}) = 0
time(NULL) = 1316942473
times({tms_utime=10433, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 943249}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 342521}, ru_stime={9, 72567}, ...}) = 0
time(NULL) = 1316942473
times({tms_utime=10434, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 944096}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 342521}, ru_stime={9, 72567}, ...}) = 0
time(NULL) = 1316942473
times({tms_utime=10434, tms_stime=907, tms_cutime=112, tms_cstime=7}) = 1718106444
gettimeofday({1316942473, 944909}, NULL) = 0
getrusage(RUSAGE_SELF, {ru_utime={104, 342521}, ru_stime={9, 72567}, ...}) = 0

It seems to be spinning within dbus_connection_dispatch, I'll see if I can come up with a backtrace.

gnome-keyring is version 3.1.92-0ubuntu1.

The system differs from a normal Oneiric install in one regard: for some reason I can't get gdm to start on login, so it actually boots into a console and I "sudo start gdm" from there. Don't know if it affects anything.

I have the same issue but gdm works just fine for me (clean install). gnome-keyring-daemon uses almost 100% cpu for about 10 seconds before stopping. It never used to do this.

This still happens in Precise.

This happens to me when I load Google-Chrome. Once it loads, it asks me for my password to unlock the keyring, the it's off to the races!

It doesn't seem to ever stop using 100% CPU (on my 3.4GHz Pentium D).

If I kill it, everything seems fine.

I have a fully updated Precise installation.

Is this the same issue? Has anyone found a workaround? Solution? Is there anything I can do to help?

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

I'm also seeing this bug on Precise with gnome-keyring_3.2.2-2ubuntu4 and libgcrypt11_1.5.0-3ubuntu0.1.

I could get a stack trace, but unfortunately without debug symbols:

After I installed the dbg package, the process was no longer stuck. Perhaps it was just stuck in a very long computation.

I can reproduce it at will by relaunching Chromium.

Here's a better stack trace with all threads:

This bug was causing my laptop (Thinkpad T500) to overheat within 5 minutes every time I started chrome. I've bought a cooling pad but it's not helping (the laptop still shuts itself).

I've found out that the issue does not come up when Google Chrome is not connected with a Google account. In other words, as a temporary workaround, one can log out of synchronisation. I don't see gnome-keyring-daemon hogging CPU any more with this option turned off.

Just making a note about similarity between this and bug #939301; latter perhaps a duplicate?

This happens to me with google chrome, but not with chromiun-browser.

If i make sure all google chrome processes are killed and restart gnome-keyring-d, it doesn't happen any more.
