A non-image file which generates a segmentation fault about sxiv

I could not reproduce the segfault. It just displays nothing and prints wrong information in the title bar.

Just tried feh on this file, it also displays nothing. Imlib2 detects the file as an image, so it's not a fault in sxiv.

Yes, with the default config.def.h it doesn't segfaults (is it
interpreted as an XPM?)

I compared my config.h with the default one and the first difference is:

#define EXIF_SUPPORT 1

It seems sufficient to produce the crash.

Nice.
One remaining problem though: 'sxiv -t clipfoo' produces a segfault if EXIF support is enabled (and an error if it isn't).

With commit ac4eb53, images without a proper format string aren't opened anymore. I hope, that this won't break any valid images. It does fix all the issues with the "clipfoo" image.
