Recurring exception

I've been getting the exception below in the last couple of EAP builds including
the current 90.122. It happens on startup, and then I get other similar looking
exceptions every few minutes. It doesn't appear to cause too many problems,
though sometimes IDEA completely falls apart and even basic editing stops
working. I've been reporting these for a while but I don't know if there's
any progress on a fix (how do I find an exception I've reported using the
IDE Fatal Errors dialog in YouTrack? IDEA displaying the URL after the bug
is submitted would be a very useful feature!)

Given that I haven't seen others complaining about it, it must be something
specific to either my project or the plugins I'm using. Does anyone have
any ideas what might be causing it?
