When you try to open incorrectly formatted history file (left from much-much older version of gnomeicu, for example) the result was a core dump in src/history.c:history_parse_chunk():sscanf().


Run gnomeicu ver. 0.99.5 and try open history with an incorrectly formatted user history file.


Apply the following patch, recompile and run:
