Relevant screenshots (Calc, Draw, Basic IDE)

(1) CALC - Renaming sheet

- click the sheet tab while pressing the Alt key.
  Delete the sheet name and validate.
  Result: AOO displays the box with message "Invalid sheet name."
          The accompanying icon: INFORMATION

- double click the sheet tab
  (or use "Rename Sheet" in its context menu)
  In the "Rename Sheet" dialog delete the sheet name and validate.
  Result: AOO displays the box with message "Invalid sheet name."
          The accompanying icon: STOP

So the same operation leads to the same message marked
by a different icon. It should not be like that
(faulty logic and bad UX).


(2) CALC - other relevant operations

- choose menu 'Insert - Sheet'
  In the "Insert Sheet" dialog delete the sheet name
  and validate.
  The message reads: "Invalid sheet name.".
  The accompanying icon: STOP

- choose menu 'Tools - Scenarios'
  In the "Create Scenario" dialo delete the scenario name
  and validate.
  The message reads: "Invalid sheet name.".
  The accompanying icon: INFORMATION

- choose menu 'Insert - Names - Labels'
  In the "Define Label Range" dialog enter an incorrect name
  (in the "Range" or "For data range" field").
  The message reads: "Invalid sheet name.".
  The accompanying icon: STOP


(3) Intercomponental consistency

- DRAW
  Attempting to enter an empty name results in a message:
  "The name chosen already exists.
   Please enter another name"
  The accompanying icon: EXCLAMATION POINT

- Basic IDE
  An attempt to approve an empty name
  (be it for BASIC module or dialog) ends with a message:
  "Invalid Name".
  The accompanying icon: STOP



Expected result (in all AOO components):
the same accompanying icon whenever possible/advisable
