Using ktown - can't start kmail

I'm using the latest ktown and multilib on an up to date Slackware 14.2+

When I start kmail from the command line I get this error

kmail: error while loading shared libraries: libqrencode.so.3: cannot open shared object file: No such file or directory

I'm convinced I'm using the correct versions

I've never ever tried starting kmail in 14.2+. I'm a Thunderbird user, but Thunderbird is giving me problems (documented in a separate thread)

I've got qrencode-4.0.2-x86_64-1_SBo installed, because I needed it to compile keepassxc.


Any suggestions?

I'll upgrade my version of qrencode in ktown to 4.x next month.
