[Pkg-xfce-devel] Bug#552991: The program 'xfce4-power-manager' received an X Window System error.

Wed Oct 28 12:54:29 UTC 2009

Package: xfce4-power-manager
Version: 0.8.4-1
Severity: normal

For a while I have seen xfce4-power-manager disappear every now and when.  I
have startet it in gdb and after a few days I got the following result:

======================================================================
Starting program: /usr/bin/xfce4-power-manager --no-daemon
[Thread debugging using libthread_db enabled]

** (xfce4-power-manager:1659): WARNING **: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.:

The program 'xfce4-power-manager' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 23108 error_code 8 request_code 131 minor_code 6)
  (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.)

Program exited with code 01.
(gdb) 
======================================================================

Doing as the error messages advises I get the following:
======================================================================
(gdb) start --no-daemon --sync

I'm keeping the gdb session running.  If anyone has any useful tips how to
proceed, please tell me.
