Version: (using Devel) Installed from: Compiled sources OS: Linux open settings -> configure kalzium -> units. set units to any other than kelvin. in 'state of matter' section, try to enter the temperature using keyboard - that is not possible.
forgot to mention, this is 4.1 beta (which could not be chosen from version dropdown here).
Might be the same than http://bugs.kde.org/show_bug.cgi?id=161067 Confirmed. I had a look at the code but there are too much calculations for my brain!
