Title:
  Segmentation fault when having IRC accounts and changing global status
  to offline

Status in Multiplatform instant messenger:
  Incomplete

Bug description:
  I get a segfault, when I turn the global status to "offline". When I
  change only the status of the IRC account, no problem. Also no
  problem, when I delete the IRC accounts and then change the global
  status to "offline".

  Debian 7.0 wheezy, Qt 4.8, latest git-Version

  Program received signal SIGSEGV, Segmentation fault.
