Sometimes I get this when I enter a cap ship:

When I run without any plugins the error doesn't pop up but I sometimes don't get a turret list.
Interestingly it seems to be rays sample repair script that triggers it. This one: http://vendetta-online.com/x/msgboard/9/17108

Not sure if it's related. During skirmishes sometimes odd goo gets written to the chat area.
In the chat area it looks like 4 unprintable characters and a newline. This is how it looks like in the log (through less):

@^W<C9>^A

Once I even got the name of a texture:

Hm, interesting. I'll try to figure out what's going on there.
