Comment (by GregorHoffleit):
For what it's worth, I get this crash on a Netgear WGT634U running Barrier
Breaker (r42625) reproducable, whenever I run the "KabelBW speed test"
(http://www.kabelbwbusiness.de/anforderungen-speedtest.html) from a client
of this router.
I haven't yet tried with a more recent build.
