NPE in DownloadFileTask

[kmspop]

Just had a crash from a mobile.
Can't reproduce it.
Probably this is our second time had this crash in a year or two, so it's a rare case.
Could you guys have a look into this?

Thank you!

Hey!
We've included fixes in the latest SDK release (5.1.1) for this. I'm closing the issue but please reopen if you run into this again.

Thx for using HockeyApp!
