A working example would be better. Anyway, citing the g_regex_match()
doc:
"Note that if match_info is not NULL then it is created even if the
function returns FALSE, i.e. you must free it regardless if regular
expression actually matched."

If your first g_regex_match() fails you have a sharp leak.
Ciao.
