Selenium RC gives Error-Object [object HTMLIFrameElement] has no method 'getCurrentWindow' while running the test in Google Chrome

Question

I am using Selenium RC and Chrome when I run the test it gives me this error

error(1340708572726): Unexpected Exception: Object [object HTMLIFrameElement] has no method 'getCurrentWindow'

However I am not always getting this error. Some times the test passes and sometime the very test fails. I changed the Browser to IE and was not getting this error. Here is the relevant part of the code

void editResumeInfo(String objective, String company, String jobDesc, String city, String phoneCountry, String phoneArea, String phoneNumb, String coleg, String certificateName, String certificateLocation, String seminarName, String seminarLocation, String notes){
        selenium.type("id=objective", objective)
        selenium.click("xpath=//html/body/div/div/div[3]/div/div[2]/div[3]/form/div/div/div[2]/div[3]/a")
        selenium.select("id=experienceIndustry0", "label=Health Care")
        selenium.select("name=experienceProfession", "label=Direct Support Professional")
        selenium.select("id=experienceStartDate0_month", "label=May")
        selenium.select("id=experienceStartDate0_year", "label=2006")
        selenium.select("id=experienceEndDate0_month", "label=August")
        selenium.select("id=experienceEndDate0_year", "label=2011")
        selenium.type("id=experienceCompany0", company)
        selenium.type("id=experienceJobDesc0", jobDesc)
        selenium.type("id=experienceAddressCity0", city)
        selenium.select("id=experienceAddressCountry0", "label=Guyana")
        selenium.type("id=experiencePhoneCountryCode0", phoneCountry)
        selenium.type("id=experienceAreaCode0", phoneArea)
        selenium.type("id=experiencePhoneNumber0", phoneNumb)
        
        selenium.click("xpath=//html/body/div[2]/div/div[3]/div/div[2]/div[3]/form/div/div/div[3]/div[3]/a")
        selenium.select("id=educationLevel0", "label=Post Graduate")
        selenium.select("id=educationDegree0", "label=Biomedical Science")
        selenium.type("id=educationCollege0", coleg)
        selenium.select("id=educationGradDate0_year", "label=2011")
        selenium.type("id=certificateName0", certificateName)
        selenium.type("id=certificateLocation0", certificateLocation)
        selenium.select("id=certificateDate0_month", "label=May")
        selenium.select("id=certificateDate0_year", "label=2004")
        
        selenium.click("xpath=//html/body/div[2]/div/div[3]/div/div[2]/div[3]/form/div/div/div[4]/div[3]/a")
        selenium.type("id=seminarName0", seminarName)
        selenium.type("id=seminarLocation0", seminarLocation)
        selenium.select("name=seminarDate_month", "label=March")
        selenium.select("name=seminarDate_year", "label=2011")
        selenium.type("id=skillNotes", notes)
        selenium.clickAndWait("id=submit")
    }

I am calling this method from

@Test
    void objectiveFiveThousandInputShowSuccess(){
        values=TestDataController.characterGen(5000)
        editResumeInfo(values, "abcd", "this is job", "bangalore", "91", "0381", "232269876", "IIT", "test certificate", "bangalore", "test seminar", "delhi", "note" )
        CheckSuccess()
    }
    
    @Test
    void objectiveFieldOnNullInputShowSuccess(){
        editResumeInfo("", "abcd", "this is job", "bangalore", "91", "0381", "232698376", "IIT", "test certificate", "bangalore", "test seminar", "delhi", "note" )
        CheckSuccess()
    }
    
    @Test
    void companyFieldOnFiveHundredShowSuccess(){
        values=TestDataController.characterGen(500)
        editResumeInfo("objective", values, "this is job", "bangalore", "91", "0381", "23269876", "IIT", "test certificate", "bangalore", "test seminar", "delhi", "note" )
        CheckSuccess()
    }
