@otini sounds like dmenu has a different PATH and/or LD_LIBRARY_PATH
@otini my money is on environment variables different (if sufficiently so they might be different binaries or using different libraries, etc.). NixOS manages to keep the window manager bits surprisingly clean and free of much user profile bits, so this isn't entirely surprising to me (if nevertheless an unfortunate situation!)
Get anything interesting from running under gdb or so? And if you're on the matrix channel I'm sure folks can help, I'll check there in a few JIC ;).
@wdtz I had a segfault in Zathura originating from somewhere in a PNG library. I'll try to investigate this further soon. Thanks for your advice :)
