When you use it will open right away but if you close it a try to open it again you have to try 3 to 6 times it varies before it will open again.

Start by reproducing the close-and-reopen sequence from the issue and compare the terminal output, especially the gee_array_list_real_get assertion, with the appmenu-gtk-module messages. Trace the failure from the reported assertion and verify that repeated reopening no longer causes the application to abort.
