Confirmed on Ubuntu 9.10, Inkscape 0.47+dev rev. 9147, with almost the same error:
---
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 109694 error_code 151 request_code 147 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.)
Program exited with code 01.
(gdb) bt
No stack.
----
You don't need to wait 30 seconds. Just select another application and go back to Inkscape.
