#8003: irssi.so: meta-L causes floating point exception in find_window_position

     Type:  defect               |    Status:  new   
Component:  finch (gnt/ncurses)  |   Version:  2.5.3 
 Keywords:  irssi FPE            |  
---------------------------------+------------------------------------------
 I use finch with the irssi wm, and when I have a buddy window open to fill
 the screen, typing meta-L to refresh causes a floating point exception. I
 will attach the backtrace in a text file because this bug reporter
 destroys the formatting.

 Seems like checking for width > 0 and height > 0 in find_window_position
 is all that is needed.
