problem with devpi test

Hi all, I'm having trouble running 'devpi test', it complains about: No matching distribution found for dja.dni (from hera_conveni_core->bt2-conveni-core==0.1.20) But the package "dja.dni" is there: $ devpi list dja.dni https://.../devpi/alex/dev/+f/e62/6a34488d42f5a/dja.dni-0.1.3.tar.gz https://.../devpi/alex/dev/+f/d5a/dd76fae3638ed/dja.dni-0.1.2.tar.gz https://.../devpi/alex/prod/+f/553/617872ee9bcb8/dja.dni-0.1.1.tar.gz Running the tests with "tox" is fine. Looking at the logs it seems that devpi is requesting the package "dja-dni" (translates the dot into a dash) while tox requests "dja.dni". Tested with devpi-server/client 2.6.0/2.5.0 and 3.1.0/2.6.2. Is there any workaround?
