cdrecord vs. K3b

Hi all, from time to time I use K3b to record data on CDROM; I think it's a nice tool/frontend... when it works. Specially, when recording data with large filenames including parenthesis () or brackets []/{}, K3b fails - I don't see any explanatory error message, just "Error"... but then I go back to cdrecord, which I use most of the time, and everything goes smooth as silk w/o errors... Is there any reason for K3b to fail where cdrecord does not? is it just a configuration issue? TIA, Martin
