Dear Maintainer,

After upgrading packages, I can't open any diaries.
When clicking on a diary in the list, or when trying to open a diary
from the command line, Lifeograph crashes with :

ERROR: Failed to open file “”: No such file or directory

** (lifeograph:65700): ERROR **: 18:17:59.162:
unhandled exception (type unknown) in signal handler


It looks like the file it fails to open is an icon. At 484 in
../src/app_window.cpp :
Lifeograph::icons->go_prev = lookup_default_icon_pixbuf(
"go-previous-symbolic", 16 );
In HELPERS::lookup_default_icon_pixbuf at ../src/helpers.cpp:2039, the
path obtained is the empty string.

I'm using the Tango icon theme, it used to work, I haven't changed icon
theme in a long time. It also crashes with "Default Gnome theme".

Changing to a different icon theme, like mate-icon-theme or
faba-icon-theme fixes the problem. Excepting that I have to find another
theme I like.
