Description japers 2015-06-18 19:46:33 CEST
Version 1.2.6-1+b1 of this plugin in Debian testing (Stretch) with all packages up-to-date.

Linux <system> 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

Selecting tachos with any combination of sensors selected causes a full system hang with the following message displayed at the top of a black screen. No controls on the system (except the power switch) are functional at this point. A forced hardware shutdown is necessary, and the condition is 100% reproducible.

*** Error in `/usr/bin/X': double free or corruption (!prev): 0x00007f53435a5c70 ***

The address reported in the error message changes each time the hang occurs.

I'm reporting this because, though it vaguely resembles some previously reported issues with the plugin, I didn't see that any of those reports mentioned a full system hang.

On our various systems running the 32 bit version of Debian testing, the systems simply lose the logged-on session, bouncing back to the login screen.

Hello,

with my Debian unstable that once was your testing, I never had such problems. I admit, selecting tachos and then restartig the panel, e.g. after logging out, will no longer allow hovering the sensors plugin, but will ínstead lead to crashes of the plugin due to some interplay problems of the plugin, Xfce, Gtk and X:

Similar with system freeze has already been reported. Using the first report for solving the issue.
