psensor does not start any more : Attempt to unlock mutex that was not locked

Are you using the stock release of psensor or a release from a PPA? Could you please give the output of the 'apt-cache policy psensor' command?

Do you reproduce systematically this issue?

Could you please:
 - ensure that all instances of psensor are stopped: killall -9 psensor
 - remove the log file: rm $HOME/.psensor/log
 - start psensor with full logging: psensor -d 3
 - attach the log: $HOME/.psensor/log

Which DE are you using? Unity? KDE?

Could you please run psensor under gdb:
 - gdb psensor
 - run
 - wait until it crash
 - bt

And send me the output.

Hi,
thanks for your fast answer.
I obviously ran with 14.04/Unity:

 - ensure that all instances of psensor are stopped: killall -9 psensor
 - remove the log file: rm $HOME/.psensor/log
 - start psensor with full logging: psensor -d 3
 - attach the log: $HOME/.psensor/log

[image: Images intégrées 1]

and I attach the file $HOME/.psensor.log

I ran as you requested:
 - gdb psensor
 - run
 - wait until it crash
 - bt

the result is in the attached file gdb

Thanks again and best regards

@Jean, thanks for the useful information.

You forget the output of "apt-cache policy psensor", I would like to know which version of psensor is concerned to try to spot the cause of your bug that I don't actually reproduce.

Sorry,
output of "apt-cache policy psensor":
maj@majquad:~$ apt-cache policy psensor
psensor:

I have another report from somebody else (directly send to my email), so I turn it into 'confirmed'.

Are you using the trusty-proposed channel?

I am still interested by the gdb information if possible. Unlike previous instructions it might be more useful to use the gdb
command 'thread apply all bt' instead of just 'bt'.

Thanks for your help.

Reporter appears to use a glib version from a ppa and not from ubuntu stock repositories.

The result of my investigation is that it is the consequence of a new check in the glib since 2.41.
It is caused by the use of the deprecated function gdk_threads_init which is only needed to workaround
a bug of appindicator < 0.2.9. The root cause is probably a bug in GTK itself as psensor does not directly
use any gdk_thread_enter|leave with appindicator3.

Fixed by http://wpitchoune.net/gitweb/?p=psensor.git;a=commit;h=43574b89d00b319eb7d7602e92a9b482ae33d760 which removes the call of gdk_threads_init when not needed.

The fix has been included in the v1.0.3 release. You can use the PPA: ppa:jfi/psensor-unstable to use it.

Thanks a lot.
I sent you the gdb.
I made no modification concerning the trusty-proposed channel.
I will try to undestand what you need to-morrow (I am just coming back).
Best regards

... I just launched psensor and it is working. I updated Ubuntu just before.

The glib package causing this issue has reached the utopic repository which means that psensor is no more working on utopic now.

The very bad news is that I cannot branch the utopic version of psensor to submit the trivial fix. It appears to be due to http://package-import.ubuntu.com/status/psensor.html#2014-04-08%2014:18:53.940182 and I can't post to the mentioned mailing list :(

As I am unable to checkout the utopic branch of psensor, submit the fix as a debdiff.

This bug was fixed in the package psensor - 1.0.2-1ubuntu4

psensor (1.0.2-1ubuntu4) utopic; urgency=medium

... it was OK with recent Ubuntu updates, but since yesterday "no graphs
ebled..." (I am running version 1.1.1).

v1.1.1 is using Gsettings instead of GConf2 (1.0.x) and the settings is not migrated so you have to redo the psensor setup. By default graph are not draw, you just have to click on the 'graph' toggle at the right of the sensor (main window).

v1.1.1 is not in the official repository and not concerned by this bug report, so I recommend to contact in another way (like send me an email to <email address hidden> or post to https://groups.google.com/forum/?fromgroups&hl=en#!forum/psensor-users) if you have questions. It is better to keep this bug report "clean".

thanks
