When previewing this file
http://www.solune.com/interne/RV_preview_crash.rvf
in RichViewActions editor, the following error occurs :
"Débordement d'entier"
The error message is in French (my Delphi and Windows language), even if RV editor isn't localised.
The message translated in English might be
"Integer overflow"

Confirmed. It may happen when previewing text formatted with raster (not TrueType) font.
Fix: Open RVStyle.pas, find two calls of RVU_GetTextExtentExPoint, change the 3rd parameter from Width*2 to $FFFFFFF.
