Title:
  crash in moveWindow

Status in Mudlet the MUD client:
  Fix Released

Bug description:
  I was on really weak wireless and after pressing Connect, Mudlet froze
  with the connection dialog open while irragularly using 100% of one
  CPU. After a while, it crashed with the following backtrace.

  I think it tried to use moveWindow before mudlets ui was fully
  initialized... or somesuch. Oneymus had a problem before with either
  resizeWindow or moveWindow and nil values (even though we couldn't
  replicate it after), and this might be related.

  SegvAnalysis:
   Segfault happened at: 0x7f629646dd1f <_ZNK7QWidget20testAttribute_helperEN2Qt15WidgetAttributeE+31>:	test   %eax,0x164(%rcx,%rdx,4)
