Bug#463772: seen the same lately

[grin]

Version: 2.4.7-1
Found: 2.4.7-1

Actually met this one now, with a mousepen tablet. Basically I cannot
use tablet and mouse together. 

If I disable all extended input sources, I can use mouse. 

If I enable the tablet, the mouse will not work; either I disable
extended input which makes no mouse events inside gimp (except menus)
or enable it, which gives coordinates around minus MAXINT, which is
probably out of bounds (and sanity) for gimp so it
throws the warnings mentioned earlier.

I have the same effect with 'xinput list', looks bad, so it might not
be a gimp problem, I cannot point to anyone though.
