inkscape crash (X error) when USB mouse is disconnected

[Andrzej]

Inkscape 0.49-dev r10505 compiled on Ubuntu 11.04, 32bit. Nvidia graphics card with a Nouveau driver. Gnome session with Compiz running.

The program 'inkscape' received an X Window System error.
This probably reflects a bug in the program.
The error was 'XI_BadDevice (invalid Device parameter)'.
  (Details: serial 8220076 error_code 149 request_code 141 minor_code 13)
  (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.)

The error occurred after a lmb click on the window.

Do you have any extended input devices (tablet) connected?

Possibly related to bug #474954 (see comment #5)?

[Andrzej (ndrwrdck)]

No tablet but I did have a regular USB mouse connected. I have disconnected it (together with power supply cable for my laptop) 10~20 minutes before the crash.

[Andrzej (ndrwrdck)]

Ok, happens every time when:
1. Inkscape is started with USB mouse plugged in
2. Mouse is disconnected
3. User clicks on the Inkscape window using a touchpad button.

My xinput devices:

$ xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Sony Sony IR Receiver id=10 [slave pointer (2)]

    ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]

I'm now trying to catch a backtrace but for some reason I can't get it just yet (no core dump, no bt in gdb, breakpoint on X11Error doesn't catch anything).

This might be similar to:

Seems like a duplicate of bug #474954 “crashes when USB drawing tablet is disconnected” to me. See also the latest comments in the other duplicate report (broken / flaky USB ports (hardware) triggering the same issue without explicitly disconnecting the USB mouse)

Thx for the backtrace!

[Andrzej (ndrwrdck)]

I agree that all these 3 bugs look like the same issue. This is actually very common error in GTK, I've just checked that gimp 2.6.11 from Ubuntu 11.04 is affected as well.

Still, it might be better to ask original reporters if they can produce a backtrace of their bugs.

For reference, this is how I made it:

(make sure mouse or tablet is plugged in)
$ gdb inkscape
$ break _XError
(answer 'y')
$ run --sync
(unplug the mouse/tablet or wait for a USB fault)
(click on the window with some other pointer)
(this should trip the breakpoint)
$ bt

I confirm that unplugging a tablet gives the same back-trace (see bug #474954, comment 7).
