m_stanzas NullReferenceException #63

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. tons of use.

What is the expected output? What do you see instead?
expect no crash, got crash

What version of the product are you using? On what operating system?
2.1.0.710

Please provide any additional information below.
This may already be fixed (i don't have svn) but in XmppStream.cs,
m_stanzas should be checked for null before attempting to write.  once in a
while it will throw a nullreferenceexception.

I had the same problem ( NullEx at XmppStream.SendNewStreamHeader ) but was not 
able
to reproduce the crash. But it turned out, I can reproduce the bug 100% now. I 
just
have to force my DSL router to reconnect. Next time jabber.net tries to ping the
server, the Exception pops up.

The line it crashes for me is:
      m_stanzas.WriteStartTag(str)

The stack trace is:

Object reference not set to an instance of an object.
