crash in requestIsValid()

[register88]

I installed transmission-daemon-2.52 on openbsd-5.2/i386, sometime it crash/exit/gone (without core dump). I posted the problem to forums ​https://forum.transmissionbt.com/viewtopic.php?f=2&t=13551 and someone suggest me use gdb to see what going on.

the result like below:

2.52 is a pretty old version.

Are you able to reproduce this issue in newer versions of Transmission?
