Sometimes and only in some applications, Openbox will randomly crash and return to login screen, forcing me to login again. I couldn't figure out when it happens, but it most notably happens everytime I open Steam and sometimes on Chromium (I managed to make it happen when flash loaded - reinstalling fixed - and random times on Facebook).
I have absolutely no idea of what is happening. There are no logs and no info on screen, nothing to help. Also, I couldn't find similar problems at other websites, neither I have enough info to fill a bug report or something.
This doesn't seem to be with Openbox at all, because on Steam this also happens with Xfce. I have not tested Chromium with Xfce.
I'm running Fedora 19, up to date, and I am almost considering moving to Arch because of this issue.
