I was trying to test the 0.15.8 11050 win client (on windows 7 system) against 0.15.8 r11099 fedora 21 server.

Not sure what triggered it - was toggling between gedit and watching video/playing with the overkill javascript at "bmw.com"... but I got the following traceback. I wasn't able to repro it, unfortunately, but I'm hoping it will be an easy to find bit of code.

Didn't seem to produce any noticeable effects, but it seemed like it was worth catching.

Disconnecting the client, I noticed this additional output, which might be of use:

This is just the usual clipboard nested loop problem, see #812.

Not much we can do about this until this is re-written.
