Arch Linux

Description:

I install converseen. When I launch it, I have this error:
╭─benoit@benoit-hp ~
╰─➤ converseen
terminate called after throwing an instance of 'Magick::ErrorModule'
what(): Magick: unable to load module `/usr/lib/ImageMagick-6.7.4/modules-Q16/coders/wmf.la': file not found @ error/module.c/OpenModule/1278
[1] 5830 abort converseen

I search for the load module. I found it:
