The latest version of feh (1.11-1) crashes when viewing images if any key is pressed or when trying to access the right-click menu.

make -> make PREFIX=/usr in the build() function should fix this.

Right. I'm taking care of that.

Xyne is still having issues with 1.11-2.

So I just found a computer which seems to exhibit the same symptoms as Xyne's:
Even if I download the feh-1.11 source tarball and just compile with a simple make, the binary I obtain does detect key events.
There is no error message...

I think my issue is unrelated to this bug.

It simply doesn't recognize keyboard input. I can access the menu by right-clicking, and left clicking changes to the next image, but pressing keys, including esc, does nothing. There is no console output and it does not crash as it in 1.11-1.

I tried using the example key configuration file (copied to $XDG_CONFIG_HOME/feh/key, i.e. ~/.config/feh/key) but that did nothing.
I also tried removing the configuration file.
Rebuilding the package using the 1.11-2 PKGBUILD produces no errors but the built package still does not recognize keyboard input.

I am on a fully updated x86_64 system.

Alright. I came up with a quick and dirty fix.
The issue here was that keystates always have the bit 2^4 set to 1 (I have no clue why); the quick fix simply ignores this bit just like feh does with the bit 2^0 (corresponding to Shift); so rather than xoring with 0x1 we xor with 0x11.
Xyne, it'd be great if you could let me know if that patch solves your issues as well.

Oh, I got it: the 2^4 bit corresponds to Mod2Mask which is the NumLock key... Turn it off and feh will work normally even without the patch.
