Comment 0 for bug 660995

Hello to qBittorrent team.

I noticed that the program (v2.4.0) has random crashes. Is hard to say under what conditions it occurs.
Sometimes it's happens through short time after run (1-2 minutes).
So, all of I have it's console output with backtrace:

user@lenovo-laptop:~$ qbittorrent &
[1] 27781
user@lenovo-laptop:~$ Peer ID: -qB2400-
HTTP user agent is qBittorrent v2.4.0
qbittorrent: malloc.c:3951: __libc_valloc: Assertion `!p || ((((mchunkptr)((char*)(p) - 2*(sizeof(size_t)))))->size & 0x2) || ar_ptr == (((((mchunkptr)((char*)(p) - 2*(sizeof(size_t)))))->size & 0x4) ? ((heap_info *)((unsigned long)(((mchunkptr)((char*)(p) - 2*(sizeof(size_t))))) & ~((2 * (512 * 1024))-1)))->ar_ptr : &main_arena)' failed.
