reportlab - bad argument to internal function error in python -
i have python script uses reportlab create report, script has been tested , works expected on occasions following error message
traceback info: file "c:\tools\legionellatool.py", line 605, in <module> createreport(selectedcoolingtowers, report_outputs_folder, dbo_colgis, openpdf) error info: ..\objects\moduleobject.c:50: bad argument internal function line 605 createreport(selectedcoolingtowers, report_outputs_folder, dbo_colgis, openpdf)
createreport function ...creates report. have debugged through code , havent got errors, might make error appear, error happens on occasions whereas on other occasions report created fine.
edit===== createreport code

in experience, intermittent errors reportlab caused problems when trying rendering text may have 'weird' in it, unexpected characters character set or nulls. looking through code didn't notice cause problem, might want possibility contains unexpected value.
in particular, i'd take @ code dealing selcontact , see if of attributes unexpectedly null or not strings lead errors.
without full stack trace, it's hard more specific.
eta
based on provided stack trace, looks problem must either going title variable trying draw or font being used draw string. looking @ code don't notice problems, though, , nothing suggest intermittent problem part of code throwing error.
