Bug#515567: gnome-system-monitor: X error if I try to change the priority of a process

[Patrick May]

Package: gnome-system-monitor
Version: 2.22.3-1
Severity: normal


Gnome's system monitor program crashed immediately if you try to set the priority of a process below 0 (that is, giving it a higher priority). 
It doesn't matter whose process it is - the result is always the same.

Steps to reproduce:

1. Start GNOME system monitor
2. Click on the "Processes" tab
3. Right click on a process, and choose "Change priority...".
4. In the "Change Priority" window, change the "nice value" to anything below 0.
For example, -3.
5. Click the "Change Priority" button.
6. The program crashes, and prints this message on the console.

The program 'gnome-system-monitor' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 39864 error_code 8 request_code 1 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.)

Heh heh! Oh, boy! Oh, man! I tested this on my laptop and my main computer, it
happened on both. Oh boy!

Just wanted to let you know.
