Description of problem:
gnome-control-center keeps crashing in libcolor.so when plugging in Datacolor Spyder 3 elite device. This behaviour continues till I unplug the device.

Version-Release number of selected component (if applicable):

How reproducible:
Log into X session and plug in the device. Happens every time.

Steps to Reproduce:
1. Install Fedora 15 as desktop and "yum update"
2. Plug in a datacolor spyder 3 elite usb device
3. Watch gnome-control-center crash continuously
Actual results:
gnome-control-center segfaults, is restarted and segfaults again till the spyder is removed:
Jul  6 20:21:11 kvm kernel: [ 2497.782933] gnome-control-c[6259]: segfault at 50 ip 00007fafaf745ba5 sp 00007fff563482e0 error 4 in 


Expected results:
gnome-control-center is started with possibilities to create an icc profile using the spyder3 usb device.

Additional info:
I will attach relevant parts of /var/log/messages and /var/spool/abrt

Here is the complete list of rpm's installed on my box

I'm not a c programmer but I'm going to try and put some more information on what might have caused this by using gdb:

[root@kvm rpmbuild]# gdb '/usr/bin/gnome-control-center color' /var/spool/abrt/ccpp-2011-07-06-18:10:42-2537/coredump

Core was generated by `/usr/bin/gnome-control-center color'.

(gdb) print panel
$1 = 0x243b430
(gdb) print panel->priv
$2 = (CcColorPanelPrivate *) 0x0

If I get this right panel->priv is a NULL reference and that is causing the segmentation fault... Can anyone comment on this?

(In reply to comment #3)
> (gdb) print panel->priv
> $2 = (CcColorPanelPrivate *) 0x0

So, this looks like either this code is being hit before the panel is instantiated (unlikely, as cc_color_panel_startup_idle_cb is setup as an idle action in the cc_color_panel_init() function, of that it's run after the panel is destroyed.

Did you have the control center open when you plugged in your device? Thanks.

Comment 5 Mark Moses 2011-08-19 10:17:03 UTC
Thanks for having a look!

I had it closed, but I also tried with control-center open. Both result in a continuous crashing.

Comment 6 Dennis Appelon Nielsen 2011-10-03 14:24:27 UTC
I can confirm this, exactly as described above.

What is happing on this bug, are there being corrected some code,there are waiting to go to Fedora repo's soon

Comment 7 Dennis Appelon Nielsen 2011-11-14 12:56:37 UTC
It is fixed with the Release for Fedora 16

Still not working with rpmfusions.net's kmod-nvidia and akmod-nvidia, but I guess that is a rpmfusion nvidia driver problem.....
