xfce4-systemload-plugin crashed with BadAlloc error

[Qianqian Fang]

Binary package hint: xfce4-systemload-plugin

My xfce4-systemload-plugin stop working after an upgrade about a month ago. This applet was running fine under 7.10, and seemed to work on after I upgraded to Hardy 8.04, however, it failed to start and show up in xfce panels after an upgrade more than a month ago.

Step to reproduce:

1. running xfce desktop
2. kill xfce4-panel process from a term
3. start xfce4-panel from the term
4. right click on the xfce panel, and select "Add New Item", then select "System Load Monitor"
5. a dashed square quickly flash on xfce panel, and disappear, nothing added to the panel
6. you can now see the error message from the term (sometimes it crashes not only the
xfce4-systemload-plugin, but also the xfce4-panel:

The program 'xfce4-systemload-plugin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 197 error_code 11 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
