Exception on opening direct messages tab

[Heiko Adams]

When trying to open the direct messages tab no messages are listed and the shell shows the following exception:

Traceback (most recent call last):
  File "/usr/bin/heybuddy", line 1006, in process_statusesXML
    data = self.get_dent_data(status)
  File "/usr/bin/heybuddy", line 1079, in get_dent_data
    data = self.xmlprocessor.get_dent_data(status)
  File "/usr/share/heybuddy/XMLProcessor.py", line 169, in get_dent_data
    if sn_html.find("class=\"attachment more\" title=\"Show more\"") != -1:
AttributeError: 'NoneType' object has no attribute 'find'

I'm using 0.2.5 rev 356
