Crash on opening containing folder right after checking files for download

[adem4ik]

It is quite rare case, but I can reproduce it constantly.

qBittorrent version: v3.3.6 Libtorrent version: 1.0.9.0 Qt version: 5.7.0 Boost version: 1.61.0 OS version: Windows 10 10.0.14393 x86_64

Preconditions: there is a torrent, that has multiple files, only a part of files has been checked for download and they has been downloaded, so torrent is in "Seeding" state

1) Click on "Seeding" status on the left panel 2) Click on that torrent in the "Transfers" list 3) Select "Content" tab 4) Check the files that hasn't been downloaded for downloading 5) Right before "Content" tab becomes empty do a right mouse click on one of the files from "Content" and click on "Open Containing Folder"

Here is the full crash info:

I reproduced from seeding, downloading, active and inactive filters.

The crash is reproduceable in v3.3.11

This is still a case in v4.0.4, but the crash log looks a bit different: qBittorrent has crashed Please file a bug report at http://bugs.qbittorrent.org and provide the following information:
