I have followed the instructions here "https://wiki.xfce.org/howto/debug" to get a gdb backtrace of ristretto.

Are you using the Moka icon theme? http://mokaproject.com/
I got the same problem with the same backtrace and it only appears when using Moka or Faba icon theme (from the same project).

[Pushpak (guanidene)]

Yes I am using the moka icon theme. I do observe that when I swtich to another icon theme, ristretto opens without an error. Can you please tell me how to fix this issue? I really like the moka icon theme and don't want to get rid of it.

[André Miranda (andreldm)]

This is not a ristretto bug, check these links:
https://github.com/moka-project/faba-mono-icons/issues/13
http://www.reddit.com/r/unixporn/comments/2bxx72/moka_icon_theme_ristretto_image_viewer_segfault/

Probably a problem with GDK and/or the Moka theme.
