--- Comment #10 from David Kredba <nheghathivhistha at gmail dot com> ---
I reported this as Calligra error but it is not. Gcc-4.8.2 can compile the same
source code. Trunk can't:

CMakeFiles/calligrasheetscommon.dir/commands/ConditionCommand.cpp.o: In

const&) const':

I think this is the same type of error.
