Thanks for testing! I didn't get that error, but "ldd src/balsa | grep enchant" shows:

        libenchant-2.so.2 => not found
        libenchant.so.1 => /lib64/libenchant.so.1 (0x00007f2f74648000)

so perhaps the linker is choosing not to link to libenchant-2 because of the conflict.

So can you check spelling without crashing?

Best,

Peter
