[sword-devel] Problems with text rendering

Dear Martin,

I believe the BPBible or Xiphos guys ran into this same problem a little
while back.  I think, after talking about it, the best solution was to
simply grab a copy on the stack, near the top of your method, and let it
go out of scope after the filter completes.

AttributeTypeList entryAttributes = myModule->getEntryAttributes();

Hope this helps.
