Mget file failure

Getting this error sometimes, could you investigate?

[lewzylu]

Does that mistake happen every time?

[reinhouthooft]

@lewzylu Only sometimes (I can't find any pattern about when it happens exactly, seems random).

[reinhouthooft]

Also, it only happens with that specific file.

I also got a similar problem. The failed file is model.aqbin

sometimes it says model.aqbin_5 is missing, sometimes it says model.aqbin_1 is missing.

[lewzylu]

Maybe there is a bug of multidownload, I’ll look at it in the next few days.

[lewzylu]

it's a bug of function ‘makedirs’ which has been fixed in 1.8.5.5.
Thx for your advice
