Comment 4 for bug 95917

I also noticed that wallpaper-tray will stop running after a period of time. I ran it from a terminal with the -v flag and clicked the tray icon to switch the image until it crashed and got the following output:
<code>

This is not the only way that it crashes though. sometimes it looks very similar but with different starting lines.
examples of starting line:
1)*** glibc detected *** wallpaper-tray: munmap_chunk(): invalid pointer: 0x081bfa78 ***
2)*** glibc detected *** wallpaper-tray: double free or corruption (out): 0x081a2890 ***
3)*** glibc detected *** wallpaper-tray: malloc(): memory corruption: 0x081afd60 ***

it also has the potential of outputting only the following line with no other information:
Segmentation fault (core dumped)

sometimes it takes a long time for it to crash and sometimes it crashes very quickly.
