mysterious crash (and no pdb symbols to get a stack trace with)

[Samuel Bronson]

I'm getting the following crash in qBittorrent v2.7.0 on Windows XP SP3 (32-bit), using the binary installer provided:

(1bfc.1088): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

Unfortunately, not having the .pdb symbols, the stack trace I get from WinDbg isn't particularly enlightening. It might be a good idea to provide those (presumably as a separate download).
