Comment # 4 on bug 1049344 from Dr. Werner Fink

Seems to be fixed in upstream version

20170715
       + modify command-line parameters for "convert" used in picsmap to work
         with ImageMagick 6.8 and newer.
       + fix build-problem with tack and ABI-5 (Debian #868328).
       + repair termcap-format from tic/infocmp broken in 20170701 fixes
         (Debian #868266).
       + reformat terminfo.src with 20170513 updates.
       + improve test-packages to address lintian warnings.

the only problem I see is that Leap 42.2 does not have ncurses 6.0 patch level
