GUI crash in gtk_cell_renderer_get_aligned_area with Menta themes under MATE

Created by: rathann

According to downstream bug, the GUI is crashing in gtk_cell_renderer_get_aligned_area() (failing the first g_assert() call) when selecting any device from the drop-down tray applet menu (About and Quit don't crash). The original reported has a receiver:

  USB id       : 046d:c52b
  Serial       : 9D2AACB0
    Firmware   : 24.07.B0030
    Bootloader : 02.09
    Other      : AA.AC

with M510 mouse and K750 keyboard paired and I'm able to reproduce this with a different receiver:

  USB id       : 046d:c52b
  Serial       : 7A7097E8
    Firmware   : 12.10.B0032
    Bootloader : 02.15
    Other      : AA.AA

with M310 and K520 paired, but not with yet another receiver:

  USB id       : 046d:c52b
  Serial       : AC5991B4
    Firmware   : 12.10.B0032
    Bootloader : 02.14
    Other      : AA.AA

with M325 and K800 paired. These are all running solaar-1.0.1. I don't see any pattern here. Any ideas?

Here's the exact GTK error:

Gtk:ERROR:gtkcellrenderer.c:1796:gtk_cell_renderer_get_aligned_area: assertion failed: (aligned_area->x >= cell_area->x && aligned_area->x <= cell_area->x + cell_area->width)
Bail out! Gtk:ERROR:gtkcellrenderer.c:1796:gtk_cell_renderer_get_aligned_area: assertion failed: (aligned_area->x >= cell_area->x && aligned_area->x <= cell_area->x + cell_area->width)
