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.

Debug:

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.
