Inkscape crashes when changing dash pattern

When I start inkscape I get a warning
$inkscape my_file.svg

(inkscape:2983): Gtk-WARNING **: Theme file for default has no directories

When I try to change the dash pattern of a line, the menu directly closes and the terminal shows:

(inkscape:2983): Gdk-WARNING **: /build/buildd/gtk+2.0-2.24.17/gdk/gdkpixbuf-drawable.c:1257: Depth of the source drawable is 32 where as the visual depth of the colormap passed is 24

(inkscape:2983): Gdk-WARNING **: Attempt to draw a drawable with depth 32 to a drawable with depth 24

(These errors are repeated 6 times)

When I reopen the pattern menu again, inkscape crashes:

The program 'inkscape' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 44320 error_code 8 request_code 62 minor_code 0)
  (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.)

It seems to be an error in the GTK2 Oxygen engine, as the crash is solved when I change the engine to Rayleigh.
