.vdi appears more than once in filenames

[barleone]

Sometimes when creating new virtual harddisks, the .vdi extension is added twice. however, at the moment, I cannot reproduce the problem, although I experienced it twice tonight. (if I could have reproduced it, I would have added printscreens to this ticket.)

maybe you can add a check right before the final creation, to make sure the .vdi extension is not twice in the filename.

i.e.: virtualharddisk1.vdi.vdi (should be virtualharddisk1.vdi)
