I debugged the process in visual studio so qbittorrent's exception handler didn't run (haven't crashed before, not sure what it does). The program crashed on this line: https://github.com/qbittorrent/qBittorrent/blob/release-4.1.0/src/gui/properties/propertieswidget.cpp#L462
m_torrent->m_nativeStatus.active_time had a value of 0xFFFFFFFF which explains the division by zero exception, but i have no idea why or how libtorrent set it to that value.

After restarting, the torrent that was probably selected has an infinite active time (it should have 3-4 hours max)

some related info from the torrent's .fastresume file:

"active_time": 16743863,
"added_time": 1529687772,
"completed_time": 1529688512,
"finished_time": 16743123,
"seeding_time": 16743123,

qBittorrent was running for 39 days and ~17 hours when it crashed (i suspend instead of shutdown)

It was fixed in some later version.
