in the channel draw callback:
  ...
  static int fbattrs[] = {
    PFFB_RGBA,
    PFFB_DOUBLEBUFFER,
    PFFB_STEREO,
    None
  };

  if (first) {
    first=0;
    pw = pfchan->getPWin();
    pw->close();
    pw->chooseFBConfig(fbattrs);
    pw->open(); /* crashes here */
  }

This gives me the following output:

PF Warn/Usage: pfMemory::unrefGetRef() Attempt to unreference memory with 0
reference count.
(repeated 6 times)

X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 143 (GLX)
  Minor opcode of failed request: 17 (X_GLXVendorPrivateWithReply)
  ...

Incidentally, if I remove the "chooseFBConfig() call", the close/open
works fine. Any help is appreciated. thanks- glenn.
