Windows crash on startup

I did a right click --> exit on the taskbar icon. Once bitcoin-qt shutdown, I started it back up. Almost immediately I got an appcrash.

The time break between 17:14:50 and 17:22:10 is when I had the appcrash screen open.

[PRabahy]

I forgot, just starting it again after the crash fixed the issue.

Could be a upstream issue: https://bugreports.qt.io/browse/QTBUG-33492
Couldn't reproduce on my Windows 7.

[Rav3nPL]

Try run it witch --debug to see more stuff in log

[PRabahy]

I can't reproduce it, so I don't think --debug will help.

CLosing this, it is weird, but there is not enough information to troubleshoot it and you're not able to reproduce it.
