Comment 2 for bug 1072389

Here is some more information from Bug #1073294 (accidental duplicate):

(1)
In addition to the configuration in the original report, the bug also occurs on Archlinux with Xfce (xfwm4 window mananger) and integrated Intel graphics; however, _not_ in an almost identical setting on a different PC with an Nvidia graphics card and nouveau drivers.

(2)
By playing around with the source code, I was able to narrow the problem down to a single GTK call: The crash occurs in sp-canvas.cpp in the function sp_canvas_item_grab, when gdk_pointer_grab is called (line 912 in the current source revision).

Again, Inkscape is the only application that exhibits this problem on my PC, even if Inkscape itself does not crash but the X server. Inkscape itself exits with "inkscape: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0." on the terminal.
