A bug in t38modem-opal3.10-patch might be causing runaway recursion --
instead of just reordering arguments to OpalConnection::AdjustMediaFormats,
it changes the otherConnection argument from `NULL' to `other'.

Please give this (untested!) patch a try.  I've added a bit of
documentation as well.

Cheers,
