Better would be to tell cppcheck you know this is ok and to ignore it by enabling the suppression filter for this "false-positive".

Put the following on the command line : --suppress=<errorid>:kwallet.cpp:203

Easiest way to get the error id is to use the --xml output type.
You can remove the line number from that suppress command to suppress all of those errors in the file, and you can set these in a file and use --suppressions suppressions.txt

(all in chapter 6 of the manual)
