Summary: XML parser error with insert fragments

Initial Comment:
Click “Fragment Library…”, select any cml fragment and click “Insert Fragment”

  1. click once on the canvas to add it --> no problem
  2. click a second time --> fragment isn’t added, terminal output reads:

:1: namespace warning : Namespace prefix (null) was not found

^

*** Open Babel Error in XML Parser
Namespace prefix (null) was not found

  1. click a third time --> 2nd fragment is added
  2. fourth time --> = second time
    …
    And when you try to add a smiles after an even number of fragment insertions, it segfaults:

#0 0xb7db5272 in OpenBabel::OBConversion::ReadString () from /usr/lib/libopenbabel.so.2
#1 0xb654faaa in Avogadro::InsertFragmentDialog::fragment () from /usr/lib/avogadro/tools/libdrawtool.so

#9 0xb722ac1b in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4
#10 0xb761cb4a in ?? () from /usr/lib/libQtGui.so.4

Not sure what the bug could be… (but the segfault is probably because the XML parser leaves OBConversion in an undefined state??)
