I have a download link (40mb+ file) when clicked and confirm where to save file, make another click on same link and got crash. 

Tried to make sample of crash, and didn't yet face such behavior: on second click app didn't made something (not showed download dialog), but also not crashed. Will provide sample as soon as got reproducible one.

Any idea what can affect such problem? 

As I see from report last triggered method was webContents.loadURL, but didn't understand why it was called since I have webContetst.session event 'will-download' called, that had to be triggered after webContents.downloadURL, not loadURL.
