Reported using DrKonqi

I reported it using DrKonqi, so I wasnt really given that option. This is what DrKonqi does, when you want to attach your report to an existing bug by default.

@Alexia? Really! this shouldn't be... thanks for the feedback. Would you like to be so kind to open a new report about that specifying the DrKonqui version and andding me on the CC list? Many thanks!!!!
