Title:
  Crash when losing IRC connection with signal SIGPIPE, Broken pipe in
  write () from /lib/x86_64-linux-gnu/libpthread.so.0

Status in “pidgin” package in Ubuntu:
  Expired

Bug description:
  This has happened several times to me when being connected to an IRC
  server with a bad connection (mobile access through phone in train)
  but I hadn't installed the -dbg package until yet, so I can only
  provide an incomplete backtrace at this point, which however looks
  pretty obvious to me:

  If necessary, I can provide a full backtrace the next time this
  happens.  I also enabled apport for future crashes...
