(process:7620): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size 
== 0' failed
Package libreoffice not installed and no hook available, ignoring


** Description changed:

  In a sheet where the range A2:A200 contain text strings and some are empty, 
the array formula
  {=SUM(Len(A2:A200))} adds one to the sum for every empty cell.
  
  {=SUM(IF(ISBLANK(A2:A200),0,LEN(A2:K200)))}, however, works correctly -
  but the if(isblank()) shouldn't be necessary.
+ 
+ It seems to be more than just the SUM function, as I tried the QUARTILE
+ function with LEN as an array function and I also got the result 1 when
+ I was expecting 0. So perhaps any time you do an array function LEN()
+ with empty cells, LEN gives 1 when it should give 0.
  
  (Needless to say the nonarray variation where you use a range of cells to 
perform the same calculation e.g.
  =LEN(A2)
  =LEN(A3)
  =LEN(A4)
  =LEN(A5)
  ...
  =LEN(A199)
  =LEN(A200)
  =SUM(B2:B200)
  
  works fine.
