#14202: IRC silently parts channel for no reason and leaves channel window open

 Keywords:  irc part cannot send to channel  |  
---------------------------------------------+------------------------------
 Pidgin is configured to auto-join a channel, in which it sits idle all
 day...

 At some unknown point, I stop receiving any new updates in the channel's
 window, because it has silently parted the channel in the background.

 I'm not sure why it's doing this, but while connected with an external IRC
 program I can see the nick pidgin is using part.  I get no feedback or
 indication at all in pidgin that this has happened, until I try to send a
 message to the channel, at which point I get a "Cannot send to channel"
 box.  The connection to the server is alive, and I can close the channel
 window and open it again without reconnecting and it'll work fine again
 until the next incident.

 I've caught it doing this twice in the debug window, but there isn't much
 of note.  Both times it seems to be doing something with MSN 2 or 3
 seconds beforehand, but I don't have any MSN plugins installed or anything
 peculiar, so I don't think that's related.  I'll include it anyway.

 This has been happening to me for months and months, since I started using
 pidgin for IRC, on 2.7.6 and 2.7.10.  I just loaded 2.7.11 so I can't yet
 verify that it's still happening, but I would be surprised if anything had
 changed.

 According to the plugins window, I have the following things checked off:

 Buddy List Options 2.6.3

 Buddy Notes 2.7.11

 Buddy State Notification 2.7.11

   Chat User List Logging 2.6.3

 Conversation Badger 2.6.3

   DiffTopic 2.6.3

 Enhanced History 2.6.3

 GtkPrplTwtr 0.5.2

 History 2.7.11

   IRC More 2.6.3

 Last Seen 2.6.3

   Markerline 2.7.11

 Message Notification 2.7.11

   Nicksaid 2.6.3

 Psychic Mode 2.7.11

 Twitgin 0.2.1

 Windows Pidgin Options 2.7.11


 This happens so intermittently that it would take months to uncheck them
 one-by-one and see if that solved the problem.  Therefore, I've decided to
 uncheck all of the clearly IRC-related ones (the ones I've indented above)
 all at once to see if that resolves the problem, but it will be a while
 before I can catch it doing it again and confirm whether either 2.7.11 or
 the disabling of those plugins had any effect.  In the meantime, hopefully
 someone can suggest some other diagnostic avenues to track this down.
