I wonder if this recent commit to the 1.8 branch would help fix this issue at least with 1.8.

  Log:
  Revert part of a change to the bridging API code

  The capabilities used in the bridging API are very different than the
  ones used for formats. When the conversion was made expanding the bit
  width of codecs, the bridging code was accidentally accosted in ways
  that it didn't deserve.

  Modified:
      branches/1.8/include/asterisk/bridging.h
      branches/1.8/include/asterisk/bridging_technology.h
      branches/1.8/main/bridging.c

As far as why svn trunk is stating that it cannot create the bridge, the debug message is not very informative as to why it couldn't create the conference bridge from what I could see briefly looking at the debug logs you posted in another message.
