a line with self defined marker crashes inkscape

[Sebastian]

Hi,
I don't think this is the sam bug as bug #511577, so I report a new bug.
With test.svg from 511577, inkscape crashes immediately. With the attached test file, the inkscape window opens and then inkscape crashes. In both cases, I get the "Inkscape encountered an internal error and will close now." window.

I created the markes with inkscape and changed some things with the XML editor.
On some lines they are ok. But when I move a node of these lines with the node tool, inkscape crashes (before I release the mouse button during dragging)
So I deactivated the markers for a line, modified it with the node tool and then activated the markers again --> inkscape crashed.
So I activated the markers with a text editor --> now, inkscape crashes when opening the file.

With the attached file, I get this output on the console (after many more gtk_misc_set_alignment assertions).

For other svg files, I get a similar output up to "Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkOptionMenu::indicator-spacing' of type `GtkBorder' from rc file value "0" of type `glong'"
