@Daniela the error might be coming from special characters in the photo’s filename, the folders in the source or output path, or metadata in the raw file. Please try these things in this order:
- Upload the raw file using http://filebin.net/ and paste the full path (source and destination) here.
- Find RawTherapee’s
executable_loaderfile (maybe @mmmtok can tell you where it is, I don’t have OS X) and above the “exec” line add these:
AppleLocale=`defaults read -g AppleLocale`
export LANG=${AppleLocale%@*}.UTF-8
See if RT still crashes after this change.
3. Eliminate all special characters from the crashing image (remove them from the filename, folders and from metadata if any) and try again.
