Description of problem:
In rsyslog we can resets all configuration variables to their default value with the global value $ResetConfigVariables but in the module code of imfile we have that (rsyslog-5.8.10-6.el6.src.rpm) we have that:

static rsRetVal resetConfigVariables(uchar __attribute__((unused)) *pp, void __attribute__((unused)) *pVal)
{
	DEFiRet;

	if(pszFileName != NULL) {
		free(pszFileName);
		pszFileName = NULL;
	}

	if(pszFileTag != NULL) {
		free(pszFileTag);
		pszFileTag = NULL;
	}	
  
	if(pszStateFile != NULL) {
		free(pszFileTag);
		pszFileTag = NULL;
	}


	/* set defaults... */
	iPollInterval = 10;
	iFacility = 128; /* local0 */
	iSeverity = 5;  /* notice, as of rfc 3164 */
	readMode = 0;
	pBindRuleset = NULL;

	RETiRet;
}

where 
	if(pszStateFile != NULL) {
		free(pszFileTag);
		pszFileTag = NULL;
	}

seems to be a copy/paste error. 

Version-Release number of selected component (if applicable):
All 5.* versions (also be reproducible on Redhat Enterprise Linux 5 with package rsyslog5)

Actual results:
	if(pszStateFile != NULL) {
		free(pszFileTag);
		pszFileTag = NULL;
	}

Expected results:
	if(pszStateFile != NULL) {
		free(pszStateFile);
		pszStateFile = NULL;
	}
