Extra info(if any)

This crash has occurred shortly after closing. Reason for closing was no d/l at all (seeding was OK), tried to Pause/Resume/[F]Resume. Perhaps related to #11375?
qbt used 1.1GB of private memory, which is high, but not the highest observed on my machine.
qbt was still happily writing out .fastresume files while the crash window was open...

This stack dump looks messed up to me, all those fe_tobytes().. also it seems might be related to libtorrent. Lets ping @arvidn.

[arvidn]

HandleTorrenResumeDataReady() should probably handle errors. Or possibly a a function ahead of it on the call stack. But the destructor should not leak exceptions.

[FranciscoPombal]

@arvidn Is this still relevant? I'd like to close this, but let me know if there is still any relevant information that you need from here or something that you'd like to investigate further.

If you have any issues with the latest version, on a supported OS, please open a new issue report.

Thank you for your contributions.
