Hedgewars: Fix cancelling video uploads
completed by: O. Michael Hartman
mentors: Andrey Korotaev, Xeli, koda
A past GSoC student introduced the possibility of recording a match to a video file and to upload it to YouTube servers directly. However if you cancel this operation while in progress, it will fail and crash the frontend at exit.
Your task is to study how QTfrontend/ui/page/pagevideos.cpp works and to provide a fix for the crash.
Please see the discussion on our bug tracker, following this link (point #11).
A working patch, that applies cleanly to our source tree. This patch should be in the form of a pull from clone,
hg export or unified diff format (in order of preference) implementing the functionality required.
