Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Upgrading from jessie to sid
* What exactly did you do (or not do) that was effective (or
ineffective)?
Unplugged my usb headset
* What was the outcome of this action?
gnome-settings-daemon didn't segfault on startup
*** End of the template - remove these template lines ***
I spent a fair bit of time diagnosing this issue. I suspect it's an upstream
bug.
The input to output mapping layer seems to misidentify the input (there's a
couple of buttons)
section of my usb headset (logitech H800) as a touchscreen input, and tries to
map it into
the gsettings layer, where the gsettings layer crashes because I suspect it's
not got a proper
GSETTINGS schema.
Attached is a gdb backtrace (with full variables showing) showing where the
gsettings set
value is called with a usb id of my headset. (046d:0a29)
Key things to notice:
1. There seem to be no debugging symbols for the gsd plugins. I had to build my
own to get them. (backtrace
here is from the packaged gsd).
2. g_settings_set_value is being called (it's not called in many places. Here
it's being called by
settings_set_display, from the input_info_remap function. It's clear that the
device code here believes
my headset is a touchscreen input device.)
3. The path being set is
"/org/gnome/desktop/peripherals/touchscreens/046d:0a29/display". I don't know
why this is failing, but it is. I suspect that other parts realize that my
headset is NOT a touchscreen
so the path is never initialized.
Hope this helps, and thanks!
Christian
