I've encountered the same problem on 10.10 too.
Running k9copy with strace I've also find the cause of the problem:
opening of an iso image returns EOVERFLOW.
>From the manual of open:
"
EOVERFLOW
pathname refers to a regular file that is too large to be opened.
The
usual scenario here is that an application compiled on a 32-bit
platform without -D_FILE_OFFSET_BITS=64 tried to open a file
whose size
exceeds (2<<31)-1 bits; see also O_LARGEFILE above. This is the
error
specified by POSIX.1-2001; in kernels before 2.6.24, Linux gave
the
error EFBIG for this case.
"

I've added the following two lines to CMakeLists.txt of the source tree and
rebuilt the deb package:
SET(CMAKE_C_FLAGS "-D_FILE_OFFSET_BITS=64")
SET(CMAKE_CXX_FLAGS "-D_FILE_OFFSET_BITS=64")
[I've put it after SET(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
line in CMakeLists.txt]
I did not test it thoroughly yet but the iso file open problem has disappeared!
These defines can cause problems only if k9copy uses external libraries
which were not compiled with the above settings and they share file
descriptors.
So I suggest this fix to be included in the official version of k9copy
too!
